Soph·ism

Sophism

n.
  1. The doctrine or mode of reasoning practiced by a sophist; hence, any fallacy designed to deceive.
    When a false argument puts on the appearance of a true one, then it is properly called a sophism, or “fallacy”.
    Let us first rid ourselves of sophisms, those of depraved men, and those of heartless philosophers.
