Quotes & Sayings About Fallacious Logic

Much blood has been needlessly spilt in history, and the Christian witness has been needlessly clouded, simply because men have equated their opinions with the authority of the Bible itself by fallacious logic. — Mildred Bangs Wynkoop

Your argument is as specious as it is fallacious. I do not give a damn that we have crossed a sea to be here. By your logic, if one was to circumnavigate the globe before being given the option of jumping off a cliff or not jumping off a cliff, you would fling yourself off immediately because - oh, my goodness - you've gone all that way and it would be a shame not to do something memorably stupid at the end. Not memorable to you, of course: you'd be dead. But everyone for miles around will always remember the day the idiot from afar threw himself to his death because, well, it would have been a shame not to. — Jonathan L. Howard

In both jokes and dreams, Freud observed, meanings are condensed and displaced, things are represented indirectly or by their opposites, fallacious reasoning trumps logic. Jokes often arise involuntarily, like dreams, and tend to be swiftly forgotten. From these similarities Freud inferred that jokes and dreams share a common origin in the unconscious. Both are essentially means of outwitting our inner censor. — Jim Holt

These were the Sophists, and their interest was in teaching the use of argumentative skills of the sort previous philosophers had exhibited, but as a means of attaining worldly success, for instance in politics. Unfortunately, they gained a reputation for being rather cynical and unscrupulous in their argumentative standards: any old argument would do as long as it persuaded one's listener, even if it was totally fallacious; what mattered was winning the debate, not arriving at the truth, and the line between logic and rhetoric was thus blurred. (The Sophists are still with us. Today we call them "lawyers," "professors of literary criticism," and "Michael Moore.") — Edward Feser
