When you are done with logic just click on me, Professor Logic, to move onto Logical Fallacies. Just make sure you have a general understanding of logic and the different types.


Logic is the study of how to make inferences and reason out problems. There are many different types of logic you can learn about but a good place to start is logic concerned with learning, thinking, and argumentation. This logic is known as informal logic and it is associated with creating sound arguments, identifying premises, identifying fallacies, and reasoning sound conclusions.

Informal logic is the best place to start in my opinion. The student of the mind will need rudimentary knowledge of other types of logic but informal logic is a great preparatory foundation. When studying logic you don’t need to study the history or biographies of the famous philosophers of old. All we need is a grasp of the methods and mechanics they employed.

On this page are links to articles and other sites where the student or logician can increase knowledge of logic. If you are following the 3 steps, focus on informal logic, then you can move onto logical fallacies. The other types of logic can be very technical to learn at first.

The Human Brain & Logic

The human brain is set up to understand the universe in a principled structured way. I’m not saying that the human brain is always logical, but that the brain filters truth by logic. When I said “understand the universe” I mean that true understanding of the universe does not involve fantasy and fiction stories. Logic is not relative, it is the absolute way of a human brain to understand a given principle at a given time. Logic dictates that an apple is an apple and not an elephant. Without there being some sort of constant by which to measure reality 2+2 might equal 389 and an apple might turn into an elephant.
