My feeling about philosophy is that it kind of got side tracked during the 20th century. In the words of John Searle, "The last 50 years of 20th century philosophy is obviously false." That includes existentialism which was proven false by a 13-year-old eight grader listening to Sarte about how meaning is different for every person. You construct your own meaning. The eight grader asked him, "Then why are you talking?" Robert Hanna has shown that so-called "Analytic Philosophy" is of historical interest only. The case is, however, even more severe. It is all about truth and meaning of words, but is totally innocent of awareness that meaning is 100 percent subjective without the slightest bit of objectivity in it. For example, the word "Dog" has meaning only to me and to whom I am talking to. In itself, it has zero relation to the dog except in the minds of people talking. [I mean to say that it has zero relevance to objective reality. And after all, what is the point of philosophy but to have an idea of what objective reality is all about. Well, here you have about 100 years of supposed rigorous philosophy which has no relevance at all to objective reality.] If you want my suggestion about philosophy, I think that Leonard Nelson is what people ought to spend time learning. That is after first getting through Kant's three critiques. You might also look at the web site of Kelley Ross who does an excellent job of getting across the main points of this Kant/Nelson approach. I might mention here the complaint of Michael Huemer about this Kant/Nelson School of thought--that is immediate non intuitive knowledge. The complaint is why would we think that implanted knowledge is true? But that is the very point of Kelley Ross in defense of this school --the very reason he resorted to Karl Popper' idea that knowledge can’t be proven. It can only be falsified. You can never prove without a shadow of doubt about any proposition, but you can disprove false propositions.And that position is not all that different from Huemer's idea of using a kind of probability theory to come to knowledge. He agrees that you can only come to truth by a long series maybe infinite series of step each one known by a kind of probability theory] The flaw in Kant is idealism along the line of Berkely and Hume. But Hegel has flaw also like the master slave dialectic. It seem to me like Plato and Aristotle in which each had important point but a 1ynthesis happened only later in Plotinus.
