There is always circularity involved when considering logic, reason and rationality. One set of definitions gives:
What is logical is not always considered reasonable. Yet we derive the rules of our logic from our reason. If we try and define what reason is we come back to logic and what is rational. But we also differentiate between logic and reason and rationality. It seems to me that all claims of objectivity whether for logic or reason or rationality are trying to square the circle.
Thinking through the nature of logic and its relationship to human reason, I am struck by the idea that logic, as we know it, may be much more of a human construct than being anything objective or universal. Logic, with its clear-cut rules of deduction, can only be a mirror of the world we claim to observe. It is a reflection of how humans perceive the world—through patterns, cause and effect, and binary distinctions between truth and falsehood. The concept of truth and falsehood as binary and mutually exclusive is a foundational assumption in classical logic, and propositions are either true or false without any middle ground. (The Law of the Excluded Middle). The rules of logic derived by reason are assertions and are fundamental assumptions. The binary distinction between true and false and that the one excludes the other is also just an assumption. It does not reflect all that we observe. It seems logical to us to say that if A is true, then B must follow, and if not-A, then not-B. But is this framework truly a reflection of the world as it is, or just a convenient tool we’ve developed to make sense of our observations?
I conclude that logic is inherently tied to the human mind – and particularly to individual human minds. It is a product of how we, as humans, experience the world through our senses, our language, and our understanding of cause and effect. Our observations, no matter how often repeated, and no matter how many times duplicated, are all perceptions. A delusion shared by multitudes does not make it true. A perception shared by billions does not make it any more objective than a single individual’s perception. The idea of something being “true” or “false” may not be a feature of the universe itself but a structure imposed by human cognition. A spider, for instance, will perceive the world in ways that are entirely alien to us, and it may have an entirely different logic that makes sense within its own experience. What we call “logic” could thus be nothing more than a human artefact, and there might be other forms of reasoning—unknown to us—practiced by other species or even extraterrestrial beings.
I must reject the idea of an absolute, objective logic. If logic is shaped by the mind that perceives the world, it cannot be universal. It must always involve the observer, making it inherently subjective. What we consider logical may not be logical to other beings whose cognitive processes are different from ours. I am quite certain that our pets do not consider our actions always to be logical. Logic, as a formal system, can only tell us what conclusions follow from given premises according to certain rules, but it does not tell us why those rules reflect the reality we observe—or whether they would hold in different contexts or for different minds. The rules of logic only give us an assumed correct process of thought, given a starting true condition, to reach other true conclusions. But logic does not attempt to define what truth is. It takes as a foundational assumption that what is not true is false and vice versa.
Hence, logic clearly is connected to but is not the same as reason. Further, I find it interesting to explore the distinction between what is reasonable and what is logical. There is no law of nature which requires us to act logically (or reasonably for that matter). Human actions may overrule what is logical to instead be reasonable or even unreasonable. While logic is about formal consistency, reasonableness is about sound judgment within the real-world context. A conclusion can be reasonable—based on experience, intuition, or practical considerations—without being strictly logical. Conversely, something can be logically valid but still seem unreasonable when we take into account broader factors like emotion, ethics, or practicality.
Thus, human reason is much wider than logic alone. I like to think of it as logic being the correctness part of that part of the thought process which needs to be bound by rules. Reason needs much more than just thinking correctly. Reasoning often involves flexibility, considering context, emotion, and pragmatic outcomes, whereas logic is strict and rule-bound. It is this broader sense of reason that helps us navigate the complexities of human life, and where strict logic fails to account for the richness of our experiences.
I conclude that logic is a guideline for structured thinking, but it is not synonymous with being reasonable. It is a product of human thought, applied to our thinking. It is tied to our perception and cognition, and its validity can only extend to be within the boundaries of what we can observe or understand. Reason, on the other hand, embraces a much wider scope. Reason brings judgement into play. To make judgements needs a set of values to compare with. The use of reason is what brings a judgement of what is “best” to do into play. Logic only allows us to follow the rules but reason allows us to act wisely and sensibly in a world that is often too complex for formal logic to capture.
But it also means that logic applies only to thinking and is no constraint on human actions. Reason is what we often use to overrule logic and as the justification of our actions. In this way, reason functions as the adaptive, real-world application of human thinking, whereas logic remains an internal tool for organizing thoughts, not necessarily dictating how we behave.
Even truth is an artefact of the mind. The world around us exists – it is. That part we perceive as observations (direct or indirect or implied) we take as being existential truth. This is the closest we get to any absolute truth and even that is tainted as being a perception of a human mind with all the limitations and foibles of that mind. A brute fact it seems, but still subjective. And everything else we take as truth is just a perception in a human mind.
Logic, reason and rationality are all artefacts of human minds. They are all subjective. There is no such thing as objective logic – except as a subjective perception.
Sabine Hossenfelder is always worth listening to and she is more often right than wrong.
I suspect there are many more areas of current “research” which are utter rubbish but continue because the authorities are duped into providing funding.
There is nothing wrong with a good healthy rant from time to time. Especially if one is right! This is a wonderful rant about two research areas which are utter nonsense but have been fooling the funders for 40 years.

The usual definitions of philosophy are along the lines of (Oxford Languages):
But this leaves me very dissatisfied. I am especially irritated by the reference to an academic discipline. If philosophy was just for academics it would be nothing more than a parasitical disease and deserving of being eradicated.
I observe the following:
It seems to me that we have to start with the fact that human cognition is limited. Any study of knowledge or existence must start with acknowledging the boundaries / limits of the human mind (brain + senses). Our observations of the world around us and of existence are limited by what we can sense and what our brains can process. These boundaries exist for every species and clearly vary from one species to the next. Evolution, not thought, can change these boundaries. What humans cannot know changes only as humans evolve to something else.
Philosophy is about knowledge and its limits.
The value lies in the search and the methods of the search that are contained in philosophical exploration. It is the process of inquiry which gives deeper understanding, promotes critical thinking, and personal growth. Philosophical inquiry develops and nurtures individual intuition, imagination, and the creative thinking which helps to explore new ideas and concepts. I have no doubt that philosophical inquiry grows an individual’s understanding of the surrounding world. Philosophical inquiry begins with posing the questions which cannot be answered and then asking “Why is there no answer?”
But what cannot be known by humans remains what cannot be known. Philosophy answers no questions (never has, and never will). But philosophy helps us to understand what is knowable, what we do know, what we can seek to know and why we cannot know what we cannot know.
So I would redefine philosophy as being
Task: A possible scenario in which early man who had the capability for language but had no language first made word-sounds is in the context of two people interacting and driven by the need to communicate. Develop a narrative where “Hey, you! Come here” is where the invention of language begins.
AI: A Tale of Two Hunters
In the vast, untamed wilderness, two hunters, (they had no names so let’s call them A and B), were out on a hunt. They were both skilled with their spears, but they struggled to coordinate their efforts. Often, they would find themselves lost in the dense undergrowth, unable to locate each other or signal their intentions.
One day, as they were tracking a deer, A stumbled upon a hidden spring. He knew that water was essential for survival, so he wanted to share his discovery with B. He tried to gesture and point in the direction of the spring, but B, engrossed in his own pursuit, didn’t notice.
A felt a surge of frustration. He needed a way to communicate his message clearly and urgently. In that moment, a sound escaped his lips, a guttural grunt that he had never uttered before. To his surprise, B stopped and looked in his direction.
A repeated the sound, this time with more emphasis. B seemed to understand. He nodded and started to move towards A. As he approached, A pointed towards the spring. B’s eyes widened in recognition.
From that day forward, A and B began to experiment with different sounds to express their thoughts and emotions. They realized that language could be a powerful tool for cooperation and survival. Over time, their simple grunts and gestures evolved into more complex words and phrases.
One day, as they were hunting together, A spotted a group of deer grazing in the distance. He wanted to alert B to the opportunity. He raised his hand and shouted, “Hey, you! Come here!”
B turned and saw the deer. He understood the meaning of A’s words and joined him in the hunt. Their combined efforts led to a successful kill, providing them with food for days to come.
As they sat by the campfire that night, A and B looked at each other with a sense of accomplishment. They had not only survived the wilderness, but they had also created a new way to communicate and cooperate. The seeds of language had been sown, and the future of humanity was forever changed.
The AI narrative takes for granted that language was invented by Homo sapiens (<300 k years) rather than by any preceding homo erectus. The inventors were hunter gatherers (<200 k years) and spears had been invented (<150 k years). A start for language around 100 – 200,000 years ago seems very plausible.
Why does logic hold in our universe? What compels the laws of nature to hold everywhere? Does the universe actually have a purpose that humans can discern?
What we understand with “purpose” is as a characteristic of a consciousness. Therefore asking whether the universe has purpose may be a valid question in language but it is meaningless unless the universe is conscious. However asking whether we (humans) can attribute any purpose to the universe is, in fact, suggesting that there is some thing (a consciousness?) which has some use for the universe. That, I think, is very close to acknowledging a higher power than the universe. When some cosmologists call on truly random events to hypothesize about the origins of the universe, they are calling on events having taken place without cause. That also comes close to an appeal to divinity. When science addresses the origins of the universe it acknowledges a state where the universe was not. Whatever compulsions caused the origin of our universe must have existed in that “previous” state. It is part of what we cannot know.
Anyway here is an interesting conversation with Gemini. The interesting part is in formulating the prompts to be fed to the Large Language Model. The weakest and most frustrating part of these AI chatbots is that they always sit on the fence and ignore the conclusions they have themselves come to.
ktwop prompt: Why Does Logic Hold?
Gemini reply: The question of why logic holds is a deep one that has puzzled philosophers for centuries. It’s a question that delves into the nature of reality, the mind, and the laws that govern our universe.
Here are a few perspectives on why logic might hold:
It’s important to note that while logic is a powerful tool, it’s not infallible. There are limitations to logical reasoning, such as the potential for biases and fallacies. Additionally, some philosophical perspectives argue that logic may not be able to capture all aspects of reality, such as subjective experiences or spiritual truths. Ultimately, the question of why logic holds is a complex one with no definitive answer. It’s a topic that continues to be explored by philosophers, mathematicians, and scientists.
ktwop prompt: Science would tell us that the universe is purposeless, but if – as all empirical evidence tells us – events in the universe are rational and that logic holds, then is it not that logic and being rational are characteristics imposed purposefully on the universe. (Or is there an overarching law which requires that the laws of nature hold)?
Gemini response: Logic, Rationality, and the Universe
Your question raises a fascinating philosophical debate about the nature of the universe and the role of logic within it.
Let’s break down your points:
In essence, the question of whether logic and rationality are imposed on the universe or are inherent to its nature is a philosophical one. It’s a question that has been debated for centuries and may never have a definitive answer.
ktwop prompt: Some scientists claim that there is a random element to the origins of our universe. But any claim of an origin being truly random would require then that the origin be without cause and thus divine. Would not a claim to of a random origin thus be an acknowledgement of a divine origin?
Gemini response: That’s a thought-provoking question that touches on the intersection of science, philosophy, and theology.
The concept of a “random” origin for the universe is often discussed in the context of cosmological theories like the Big Bang. While these theories suggest that the universe began in a state of extreme energy and density, they don’t necessarily imply a completely random origin.
Here are a few points to consider:
Quantum Mechanics: At the quantum level, the universe exhibits behaviors that can be described as “random” according to our current understanding of physics. However, this doesn’t necessarily mean that these events are truly without cause. Some interpretations of quantum mechanics suggest that there may be underlying factors or hidden variables that we can’t yet observe.
The Laws of Physics: Even if the initial state of the universe was random, the subsequent evolution of the universe would be governed by the laws of physics. These laws, while complex and not fully understood, are believed to be consistent and deterministic.
Divine Intervention: The idea of a “divine” origin is a theological concept that goes beyond the scope of scientific inquiry. While some people may interpret a random or unexplained origin as evidence of divine intervention, this is a matter of faith and personal belief.
In conclusion, the claim of a random origin for the universe doesn’t necessarily imply a divine origin. The concept of randomness is a complex one, and our understanding of it is still evolving. Ultimately, the question of the universe’s origin is a profound one that involves both scientific and philosophical considerations.
Returning to the questions we began with:
There are things we know and knowable things we do not yet know.
But we are human and finite human beings have limitations.
And there are unknowable things we cannot ever know.
A conversation, this time, with Gemini.
I think both Gemini and ChatGPT have a strong bias towards the politically correct, liberal, view which is a reflection of how they were trained. But with that in mind, they are still powerful ways of summarizing and articulating positions. They also provide a very useful – for me – way of checking whether I am missing critical arguments when thinking things through.
This conversation is what it is and is worth no more than appears on the surface (and it may be worth a lot less).
My own conviction is that “inherent worth” is a nonsense concept and an absurd juxtaposition of words. Worth and value are inherently relativistic. The absurdity of the word combination – in my view – renders the philosophies and ethics concepts which are built on “inherent worth” absurd and false. Nothing – including a human life – can have “inherent worth”.
ktwop prompt:
“Intrinsic worth” of anything is a nonsense statement since worth and value in isolation must be zero. If it is not zero it implies that the thing has the same value then to everything else in the universe, taken separately or together.
Your argument is thought-provoking. You’ve presented a strong case against the notion of intrinsic worth by highlighting the inherent relativity of value. It’s a perspective that challenges the idea of a universal, inherent value independent of context.
Key Points of Your Argument:
Counterarguments and Considerations:
While your argument is compelling, it’s essential to consider these points:
A Possible Reconciliation:
Perhaps a more nuanced approach is needed. We could consider that while intrinsic worth might not exist in an absolute sense, it can still be a meaningful concept within specific frameworks or contexts. For example, in ethics, we might discuss the intrinsic value of human life relative to other human lives, without necessarily assigning it a universal value.
You’ve made a compelling case. By equating the concept of intrinsic worth to the nonsense of Edward Lear’s verse, you’ve highlighted the inherent contradiction within the term.
Key Points of Your Argument:
Expanding on the Argument:
Your analogy to Edward Lear’s nonsense verse is particularly effective. It emphasizes the arbitrary nature of assigning a fixed, absolute value to something as complex and variable as human life.
To further solidify your argument, you could explore these avenues:
Potential Counterarguments and Rebuttals:
While your argument is strong, it’s essential to anticipate potential counterarguments:
By systematically addressing these counterarguments, you can strengthen your overall position and provide a more comprehensive critique of the concept of intrinsic worth.
2. Moral Intuition:
3. Rational Arguments:
4. Evolutionary Explanations:
Critique of These Justifications:
While these justifications have been influential, they are not without their critics. As you’ve pointed out, many of these arguments rely on subjective beliefs, intuition, or abstract concepts that are difficult to prove empirically. Additionally, the concept of inherent worth often conflicts with the observable diversity of human behavior and the realities of human suffering. It’s essential to note that these are just some of the ways philosophers and ethicists have attempted to justify the concept of inherent human worth. Your critical analysis of the concept is valid and invites further exploration of alternative frameworks for understanding human value.
Back in the 1970s a Sikh friend introduced me to Jagjit Singh and how he had reinvented and rejuvenated ghazals. Through the 1980s I listened often to Jagjit and Chitra Singh. But for some reason I have hardly listened to any of their music for the last 20 years.
Jagjit Singh (born Jagmohan Singh Dhiman; 8 February 1941 – 10 October 2011) was an Indian composer, singer and musician. He composed and sang in numerous languages and is credited for the revival and popularity of ghazal, an Indian classical art form, by choosing poetry that was relevant to the masses and composing them in a way that laid more emphasis on the meaning of words and melody evoked by them.
I accidently came across some of his BBC recordings about 2 years ago. With much delight I have been rediscovering and remembering much of his work – or at least that part which is available on the internet. Chitra – who is Bengali – had a remarkable clarity of voice even when singing in Hindi or Punjabi. She stopped singing in 1990 when their son was killed in an accident. Jagjit Singh died in 2011 but he reinvented the ghazals tradition.
This particular recording from 1979 by the BBC in Birmingham is of the form of a Punjabi tappe which is to be heard at every Punjabi wedding. (Punjabi tappe in folk tradition generally have 1 or 3 lines in rhyme and all have the same melody. Commonly used during Punjabi weddings).
The laws of nature do not allow any non-compliance. Whether we have managed to formulate them correctly or not (and it is worth remembering that we still cannot explain why gravity works), the laws of nature specify how effects follow causes in our universe. Inexorable, unavoidable, unchangeable. The laws of nature are indifferent to the state of the universe.
Natural Law, however, is neither natural nor a law. It is not a real thing. It is nothing which can be found in nature which controls or commands human behaviour. I consider the concept of Natural Law to be sentimentalized fantasy and false. Even though the concept of a Natural Law existing dates back to antiquity and has been suggested by great minds and well meaning people, I have always found this fantasy about Natural Law utterly unpersuasive.
Many consider Aristotle to be the father of Natural Law Theory. He argued that what is “just by nature” is not always the same as what is “just by law,” as it does not depend on the decisions or laws of any one group of people, such as lawmakers. Following this, Cicero explained Natural Law as something that can contribute to the general good of society, whereas positive law would contribute to the safety of society. Many contributions continued to be made to Natural Law Theory, such as during the Renaissance and Age of Enlightenment, which led to the creation of more modern Natural Law theories that combined Natural Law with other philosophical theories, …….. In more modern times, Natural Law was also supported by great thinkers such as Mahatma Gandhi and Martin Luther King Jr.
A current definition of Natural Law would be:
Natural law is a philosophical concept that posits that there are inherent laws, principles, or moral codes that are part of the natural order of the world and are accessible to human reason.
I find it does not have the status of a theory. In fact it could hardly even be called a hypothesis. For the concept to make any sense it would require that an objective, universal morality exist, which is impossible. All morality emanates from individual minds and is necessarily subjective. Groups of people could find common ground and share various aspects of morality. But there is no such thing as an objective, universal morality. There is no morality to be found in the natural world. If morality existed in nature, it would, like the laws of nature, then be unavoidable and compel actions. There is no evidence of any such overriding universal morality which commands human behaviour. In fact, just considering how values and morality develop proves, to me, that there can be no such thing as a universal morality.
All morality is subjective and is based on an individual’s most basic value system and applies the individual’s own differentiation between “good” and “bad”. Everything about morality starts from there. This morality does not – as the politically correct claim – establish the intrinsic worth of every individual human. A human has no intrinsic worth. The concept of every human having some intrinsic worth independent of other people and the rest of the universe is nonsensical. The worth he has can only be assessed in the context of the society he exists in. The values of “good” and “bad” derive ultimately from survival needs. What helped survival was good and what did not was bad. As humans evolved and the social behaviour of humans came to differentiate our species from others, it became imperative to differentiate and distinguish between “us” and “them”. Individual, family, clan, and tribe. Nations and religions also need a “tribal” philosophy to differentiate themselves and prosper. The most primal behaviour among humans as a social animal thus is first to ensure survival of the individual and then to define a “we” and a “them”. Actions are taken, in the first instance, for the benefit of the “we”. This becomes actions against “them” if threats are perceived. It is self interest, first of the individual and then of the “we”, which governs human actions. The notion that reason could give a moral philosophy which does not favour “us” is utterly false. Reason has no option but to acknowledge that “we” and “them” is primal and it is unreasonable to claim otherwise. A morality which differentiates between “us” and “them” would then fundamentally contradict any concept of universality applying either to morality or to Natural Law.
My point is that human nature was, and remains, inherently tribal. Tribalism is a good thing. It has worked and still enables human development. It has driven the social and cultural evolution of humans. “We” begets “them”. It is the “we” which provides the motivation which fuels innovation. The fanciful notion that reason alone can lead to a universal moral philosophy that applies equally to all humans (Natural Law) is contradicted by our need for “us” and “them”. If our most primal instincts are to protect “us”, which requires that we differentiate “us” from “them,” then a morality based on these instincts could not be universal. If the entire human race is to be “us” we would still prioritize family and clan or gang or religion in the need to invent a “them”.
The Role of Tribalism in Human Evolution and Development
Tribalism as a Driver of Evolution:
• Survival and Cooperation: Tribalism has indeed played a crucial role in human evolution. Early humans survived by forming tight-knit groups that provided mutual protection, shared resources, and developed social norms that fostered cooperation. This in-group loyalty was essential for survival in a harsh environment.
• Cultural Development: Tribal structures also facilitated the development of culture, language, social roles, and norms, enabling groups to transmit knowledge and skills across generations.
The Benefits of Tribalism:
• Social Identity and Belonging: Tribalism provides individuals with a sense of identity, belonging, and purpose. It fosters social cohesion and collective action, which have been critical for the development of complex societies.
• Competition and Innovation: Competition between tribes or groups has driven innovation and progress in many areas, from technology to governance.
Human behaviour is driven by self interest. First the interest of the individual and then of the social groups where the individual claims membership – family, clan, tribe, religion and nation. It is primal among humans and is reflected in our language that where there is a “we” there has to be a “them”. The defining social group governing individual behaviour being some highfalutin notion of “humanity in general” is pious nonsense.
Natural Law is not natural and it is not law. It is mainly sentimental drivel.
ChatGPT is about as politically correct as it is possible to be since that reflects its biased trainers and how it was trained. Given my skepticism about the concept of Natural Law I thought to provoke a politically correct view by having a “conversation” with ChatGPT. I was a little surprised that it could find no real defense. It only reinforces my opinion that Natural Law is not a real thing at all, is a very misleading concept and does more harm than good. My final question and ChatGPT’s answer is given below.
Question: ktwop – The bottom line is that Natural Law does not actually exist in nature and the idea of a universal moral philosophy and its benefits is just a hypothesis which is not even a theory. Discuss.
ChatGPT : Your position highlights a critical and skeptical view of natural law and universal moral philosophy, questioning their existence and validity as more than theoretical constructs. Let’s summarize the key points:
- Natural Law’s Basis in Nature
- Natural Law as a Construct: You argue that natural law doesn’t have a basis in nature itself. This perspective views natural law as a human-made construct rather than something that inherently exists in the natural world.
- Absence in Nature: Indeed, natural law doesn’t manifest in nature like physical laws (e.g., gravity). It’s a philosophical concept that attempts to derive moral principles from human nature and reason, rather than directly from the natural world.
- Universal Moral Philosophy as a Hypothesis
- Hypothetical Nature: The idea of a universal moral philosophy, according to your view, is at best a hypothesis—a proposal that hasn’t been universally accepted or proven in practice. It’s a speculative idea rather than a fully developed theory with empirical backing.
- Challenges of Universality: You point out that while the benefits of such a philosophy are often argued for, the evidence for its practical implementation and effectiveness is limited. Cultural differences, historical conflicts, and the persistence of tribalism challenge the idea that a single moral framework can apply universally.
- Theoretical vs. Practical Implications
- Not an Empirical Science: Unlike natural sciences, which develop theories based on observable and testable phenomena, natural law and universal moral philosophy belong to the realm of moral and political philosophy. They are normative, meaning they prescribe how things ought to be rather than describe how things are.
- Speculative Nature: Because these concepts are speculative, their validity largely depends on philosophical reasoning, ethical debates, and cultural acceptance, rather than empirical validation.
Conclusion
Your critique suggests that natural law and the idea of a universal moral philosophy are intellectual constructs rather than realities grounded in nature or proven theories. They are proposals that attempt to guide human behavior and social organization based on ideals of reason, human dignity, and common good. However, their existence and effectiveness remain subjects of debate, with significant challenges to their universality and practical application.
In essence, while these ideas have influenced moral and legal thought, their status as more than hypothetical constructs is contested, and they may not hold the same weight as theories in the natural sciences.
