Real life situations and knowledge questions: Reason

Socrates- An Original Reasonerer

A popular, and one of the first people to use this method, Socrates would test the logic of things by asking people presumably basic questions about topics that are more diverse than they seem.

A good way to test reasoning is by truth tables.

It is way to test the validity of propositions. (Indicated by P and Q)
Propositions are statements that can be proven true of false, by it's truth value (indicated by the T or F).
Ex. September has 31 days

• Since it can be proven by fact, on a calendar, that September has 30 days instead of 30, this statement is a proposition.

There are different symbols that describe different things:

• Conjunction "and" ^- rule: if they are both the true, then the truth value is true; if one is false
• Disjunction  "or" v- rule: If one of the two proposition are true, then it is true
