50 powerful principles for clear and effective thinking, or How to think logically

What do the ancient Greek philosopher and a person who received insurance for cigars he himself has smoked have in common? Both engaged in thinking – with different motivations, but with the same inventiveness. This book invites you on an... exciting journey through the labyrinths of logic, analysis, and common sense. The author effortlessly combines anecdotes, philosophical ideas, and practical advice to show how to develop truly clear thinking.


The book collects 50 principles that help understand how our perception works, how errors in logic arise, how to recognize manipulations, analyze information, make decisions, and reason soundly, without getting lost in emotions and stereotypes. You will build an internal system of logical thinking that you can rely on in difficult situations, in work and personal disputes, when analyzing any sources. From the Socratic method to modern models and tasks – you will receive a versatile practical guide useful regardless of your level of preparation.
 

The author respects the reader: without moralizing and pressure, he offers to rethink how we see the world. Instead of a categorical "do it this way" – a gentle but confident "here is how you can do it." This book does not teach what to think – it shows how to think: clearly, deeply, and independently.
