Finding proofs for falsehood

George MacDonaldNo man ever yet entertained an unhappy suspicion but straightway an army of proofs positive come crowding to the service of the lie. It is astounding with what manifest probability everything will fall in to prove a fact which has no foundation whatever! There is no end to the perfection with which a man may fool himself while taking absolute precautions against being fooled by others . . . Every . . . fact has endless side and relations; but of all these, the man whose being hangs upon one thought will see only those sides and relations which fall in with that thought.
