FIDELITY AS A PROOF OF VALIDITY
It is a perfect sign of a sound theory if during forty years its originator does not mistrust it; but I maintain that there has never yet been a philosopher who has not eventually deprecated the philosophy of his youth. Perhaps, however, he has not spoken publicly of this change of opinion, for reasons of ambition, or, what is more probable in noble natures, out of delicate consideration for his adherents.
