The usual definitions of philosophy are along the lines of (Oxford Languages):
- the study of the fundamental nature of knowledge, reality, and existence, especially when considered as an academic discipline.
- a theory or attitude that acts as a guiding principle for behaviour.
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:
- Philosophy only deals with unanswerable questions. The study of philosophy “increases understanding” but has never, ever, conclusively or finally, answered a question.
- For the decidedly finite human mind (brain + senses), there are many things which cannot be known.
- What cannot be known is a function of the mind (senses + brain = species) in question.
- What a dog cannot know is different to what a chimp cannot know. What homo sapiens cannot know today is different to what homo superior will not be able to know sometime in the future.
- As species evolve the unanswerable questions change.
- Where a question has an answer, it is not philosophy.
- Philosophy is about first posing questions that cannot be answered. Then it is about seeking answers and the methods of seeking answers.
- Philosophy may increase understanding of the difficulties of finding answers to particular questions and help to set limits around the questions, but never has (and never will) definitively answer such fundamental questions
- We are no closer to knowing the nature of reality, truth, existence, consciousness, causality, time or knowledge now than we were 10,000 years ago.
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
