‎''I can only estimate the strength of affection if I have performed an action by which it is defined and ratified. But if I then appeal to this affection to justify my action, I find myself drawn into a vicious circle.In other words, feeling is formed by the deeds that one does;therefore I cannot consult it as a guide to action. And that is to say that I can neither seek within myself for an authentic impulse to action, nor can I expect, from some ethic, formulae that will enable me to act.''
