Is logic to be trusted?

  How is Aristotelian logic related to modern science?

  It has especially close connections to mathematics, computer science, and philosophy. Both Aristotelian logic and modern symbolic logic are impressive bodies of knowledge that constitute major intellectual achievements. Fallacious thinking—in the form of propaganda, exaggeration, misdirection, and even outright lies—abounds in our culture.
