I think it was in 4th grade elementary school, that I first heard of logic. The teacher introduced it, with some examples to illustrate the use of logic. I recall that it seemed rather easy to do logic. All that I had to do was use clear thinking. So I never did actually try to learn the rules of logic. I just went by clear thinking, as appropriate.
I am posting this as one of the posts on my own views of philosophical topics. No doubt my view of logic is partly shaped by the fact that I am a mathematician. And, as a mathematician, I of course use a lot of logic. But my basic view is still much the same as in 4th grade. That is, I see logic as clear thinking. It is a formalized or formalizable view of clear thinking, but it is nevertheless something that comes from clear thinking.
