In this world are very few things made from logic alone. It is illogical for man to be too logical. Some things we must just let stand. The mystery is more important than any possible explanation. The searcher after truth must search with humanity. Ruthless logic is the sign of a limited mind.

Unfortunately, I think that's one of the last things that gets factored in when you're assembling a cast.

Every song has a composer, every book has an author, every car has a maker, every painting has a painter, and every building has a builder.

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.

To which do we pledge allegiance?
