The placement of the rectangular plates followed a strict logic in that the plates tilted away and towards the center line in an asymmetrical counterpoint.

I care not for the theoretical symmetry and impregnable logic of your moral code, I care not for the hoary respectability and traditional mysticisms of your theological institutions, I care not for the beauty and solemnity of your rituals and religious ceremonies, I care not even for the reasonableness and unimpeachable fairness of your social ethics,--if it does not turn out better, nobler, truer, men and women,--if it does not add to the world's stock of valuable souls,--if it does not give us a sounder, healthier, more reliable product from this great factory of men--I will have none of it.

Just accept my word for it on faith. And that's just the logic theists use in their discussions of evil.

When the logician has resolved each demonstration into a host of elementary operations, all of them correct, he will not yet be in possession of the whole reality, that indefinable something that constitutes the unity ...

It will therefore appear to him an idle and ineffectual proceeding to say that there is a reason for his present failure. Nevertheless, it may be well to say it, and to try and make it clear even to him.

God wants us to give charity because it's the right thing to do.
