Edith Wharton,
Tales of Men and Ghosts — The Debt
(1914)
“ Dredge laughed, but not unkindly. “My dear Archie, your father wasn't one of the kind who bother to defend their case. Men like him are the masters, not the servants, of their theories. They respect an idea only as long as it's of use to them; when it's usefulness ends they chuck it out. And that's what your father would have done.”Archie reddened. “Don't you assume a good deal in taking it for granted that he would have had to in this particular case?”Dredge reflected. “Yes: I was going too far. Each of us can only answer for himself. But to my mind your father's theory is refuted.” ”
