Use a lógica: um guia para pensamento eficaz

The book emphasizes practical thinking skills — I'm curious what motivated the author to make this a personal development guide rather than a pure philosophy text.

Many of the illustrations about common fallacies or reasoning errors felt very modern. Did these examples help clarify logic in ways that stick for others too?

The principles of logic can sometimes feel rigid — I wonder how the book addresses avoiding over-cynicism while still questioning assumptions.
