I think a man`s duty is to find out where the truth is, or if he cannot, at least to take the best possible human doctrine and the hardest to disprove, and to ride on this like a raft over the waters of life
Plato
Christianity, with its doctrine of humility, of forgiveness, of love, is incompatible with the state, with its haughtiness, its violence, its punishment, its wars
Leo Nikolaevich Tolstoy
A doctrine capable of being stated only in obscure and involved terms is open to reasonable suspicion of being either crude or erroneous
Frederick Pollock
The (Christian) "doctrines" are translations into our concepts and ideas of that which God has already expressed in language more adequate, namely the actual incarnation, crucifixion, and resurrection
C.S. Lewis
