Courses in formal logic and systems thinking: do they exist?

Question

IT education

For html\css\js courses - heaps, they are everywhere. It would be desirable on formal logic and system thinking. There are books on both. Well, toys like Sudoku :) But I haven’t seen courses on the Russian-speaking Internet. Maybe in the English part? What do you advise?

Answer 1

Read "Harry Potter and the Methods of Rational Thinking" (hpmor.ru)
And from there the articles on lesswrong.ru show
very well what rationality and logic are.

Answer 2

There is no systemic thinking
System - translated from Greek Whole
Thinking and logic are -
Male or female
Adult or childish
Healthy or schizophrenic
Usually people are taught to learn and think and reason by good teachers at school
If this was not the case before the age of 15, then it is almost impossible

Answer 3

Somehow I saw a book with logical tasks like: one says one thing, the other - another, the third - the third. Determine who is lying. "Occam's Razor" is also a chain of reasoning. That's kind of interesting.
