Perhaps the greatest philosopher of his time, and surely one the greatest philosophers of all time. Aristotle was alive in Greece from 384-322 B.C.
Aristotle is well remembered for his development of "
logic." Do note that he did not (obviously) invent logic, however greatly influenced its progression.
His format on which he based his logic was used for centuries after his
death -- and much is still echoed even today.
Specifically, Aristotle produced provocative arguments and commentaries centering around humanity and
human functions. Among them: the singular lifestyle that, if adopted plurally, would yield true and sustained
happiness to all --
forever. However, after hearing a lecture on the subject, you truly need not look any further than the utopias and dystopias illustrated throughout literature, such as in "The Giver" or "Brave New World." Aristotle'
s philosophy on 'true
happiness,' perhaps original for its time, has become almost as common as a cliche' and just as easily passed off as "wishful thinking."
However, the beauty of logic is that it never actually needs to be congruent with realism.
Aristotle
said:
"The
individual, when isolated, is not self-sufficing, and therefore he is like a part in relation to the whole. But whoever is unable to live in
society, or who has no need of it because he is sufficienct for himself, must be either a beast or a god."
