From A History of Psychology in Autobiography, B.F. Skinner says:
In both my writing and my research I have fought hard against deceiving myself. I avoid metaphors which are effective at the cost of obscuring issues. I avoid rhetorical devices which give unwarranted plausibility to an argument (and I sometimes reassure myself by making lists of the devices so used by others). I avoid the unwarranted prestige conferred by mathematics, even, I am afraid, when mathematics would be helpful.
