But love is many things, none of them logical.

If pressed to supplement Tweedledee's ostensive definition of logic with a discursive definition of the same subject, I would say that logic is the systematic study of the logical truths.

In elementary school, in case of fire you have to line up quietly in a single file line from smallest to tallest. What is the logic? Do tall people burn slower?

If scientific reasoning were limited to the logical processes of arithmetic, we should not get very far in our understanding of the physical world. One might as well attempt to grasp the game of poker entirely by the use of the mathematics of probability.

Life would have no consequence, If all I saw made perfect sense. Life would not be magical, If all I saw was logical. So I question all I see, To try and solve the mystery. I've been living under delusion, Led astray by my confusion.

The Army has carried the American . . . ideal to its logical conclusion. Not only do they prohibit discrimination on the grounds of race, creed and color, but also on ability.

Even among humans, morality is ignored when expedient. Why should we expect more from an alien life form than we demand from ourselves?"
