Depressie won’t even come close to this hell.

[Stoney]

I actually found this really interesting despite the technical jargon. Obviously this isn’t a life changing book but now I can better understand other books I want to read.

[Phine Hazelbag]

Ik spring nog liever uit een vliegtuig dan nog één keer het vak logica voor filosofen te moeten volgen

[Screw Driver]

Too much focus on natural (English) language. Natural languages suck, might confuse newbies.

[Niels]

A very clear explanation of formal logic, I enjoyed it a lot!

[Nancy Dinan]

Thank God it’s fucking over, swear down this Moduele nearly killed me. Now just the exam left 🥲🥲

[Ahmad A.]

A very precise, brief and by far the shortest introduction to Formal Logic I have read. Very good.

[Juliette Whiteside]

One of the easiest to follow textbooks I’ve encountered thus far. Also the first textbook I’ve ever read from start to finish. 😎

Bit boring like

[Ming Chen]

Read an edited version for a university logic course. A good introduction to formal logic.

[Areus]

Mis condolencias a todos aquellos que tienen que leer esto para la universidad.

[Travis Kim]

This wasn’t that logical to me 🤦‍♂️

[Zugzwang]

A decent textbook to learn about the foundation structure of formal logic

[Paul]

I did not learn much at all past the early chapters of the book.

I don’t know what it is, but the method of explaining things used in most of this textbook is so mind numbingly boring that I could not focus.

I have struggled all semester with my Intro to Formal Logic course and I blame this book and my professor about equally.
