Emotions are not tools of cognition . . . one must differentiate between one’s
thoughts and one’s emotions with full clarity and precision. One does not have
to be omniscient in order to possess knowledge; one merely has to know that
which one does know, and distinguish it from that which one feels. Nor does one
need a full system of philosophical epistemology in order to distinguish one’s
own considered judgment from one’s feelings, wishes, hopes or fears.
