A J Ayer's Language Truth and Logic

Meet philosophy's worst idea ever, touted by geniuses. That's how it goes. Did anyone say brains are wisdom? They aren't.

I read this book. I was a fan of analytic philosophy, so without a single doubt I must do it. Well, I do like the style of Ayer, however can't say it was an easy reading for me so I'm planning to reread this. Besides, I do not like when about philosophical ideas is said that 'it's a mistake'. Really? A philosophical idea is a mistake? How possible is it?

A useful philosophical method — Do not vigorously condemn opinions or beliefs which you or which others appear to hold strongly — simply to annoy them — or simply to annoy yourself.

Do not demand evidence or justification for beliefs which others hold strongly.

Ask yourself why you don’t support the opinions which other men hold?

The answer to the problem of induction is that generally speaking there is no such thing as induction. We KNOW that the past causes the future not by experience, but because that is what we define the past and future to be - precisely cause and effect in the general. Similarly for the specific: we KNOW how billiard balls and coffee cups behave precisely because if they behaved in any other way they would NOT be billiard balls or coffee cups, they would be illusions or tricks or hallucinations, but not the truly described physical object.

The problem of induction arises from a misunderstanding as to what a physical object is: that is a vector or connector in the network of causality. Hume extracts some trivial aspects of an object to create a sort of sudo-object removed from its causal net, and then says: "look causality doesn't exist!"

But there are only the two theories. My theory says some philosophical theories can be wrong. Your theory says mine is wrong. But if yours is right, then mine is wrong and so yours is wrong also.
