"How does logic lead man in a search for truth?"

Yahoo search pinged my site for this phrase, although it was so mis-spelled that I wondered for a few minutes about the searchee's logic, humanity, and vision of truth.

However...

Logic is a method, some say the primary method, of the exercise of man's rationality. Logic is the tool that man uses to reason. Man's rationality is his ability to attain knowledge or understanding by moving from one thing to another.

Man, by exercising logic, comes to know the explicit truth of many things he previously did not know.

Now, some argue that the syllogism is not the method by which he does that, and that, in fact, the truth in the conclusion of the syllogism is inherent in, and contained in the premises. This would define the syllogism as a formal mode of presenting truth, but not necessarily an instructive mode.

More on this later...
