A sophist (Greek: σοφιστής, romanized: sophistes) was a teacher in ancient Greece in the fifth and fourth centuries BC. Sophists specialized in one or more subject areas, such as philosophy, rhetoric, music, athletics, and mathematics. They taught arete – "virtue" or "excellence" – predominantly to young statesmen and nobility. In the present day, however, a sophist refers to someone who deliberately argues using fallacious arguments … WebThe astrolib function sphdist provides an alternate method of computing a spherical distance.
