"Man can be defined as an animal that makes dogmas.
As he piles doctrine on doctrine and conclusion on conclusion
in the formation of some tremendous scheme of philosophy
and religion, he is, in the only legitimate sense of which the
expression is capable, becoming more and more human.
When he drops one doctrine after another in a refined
scepticism, when he declines to tie himself to a system,
when he says that he has outgrown definitions, when he
says that he disbelieves in finality, when, in his own
imagination, he sits as God, holding no form of creed
but contemplating all, then he is by that very process
sinking slowly backwards into the vagueness of the
vagrant animals and the unconsciousness of the grass.
Trees have no dogmas. Turnips are singularly broad-minded."
G. K. Chesterton, Heretics, Ch. 20
