"According to my non-completely integrated yet concise theory (will be completed after enough years, due to lack of time!) for the: (Ultimate) philosophical bases of differential psychology & psychometry (or else: The "post"-quantum bases of philosophical psychometry),...Ludwig Wittgenstein was a "philosophical monster" of intelligence (with also a "tremendous" "mental vitality" & "(mental) creativity", very close to this of the absolutely unique global phenomenon/in these parameters: Friedrich Nietzsche).

The Austrian Wittgenstein (1889-1951)/a son of an industrial magnate (and..."never" of an average person!...-physical law of the ultimate genius's "birth"-), as the greatest "analytic" philosopher/who had 170-i.q. (equal to this of Albert Einstein/-and Einstein wasn't the top history's physicist!-) stands as the number 4 ranked philosopher in world's history, after the three ultimate philosophers (all of them existed within 19th century): Ludwig Feuerbach-180 i.q. (1804-1872), John Stuart Mill (number 1/ranked)-190 i.q. (1806-1873), & Friedrich Nietzsche-also 180 i.q. (1844-1900).

Within 20th century, these certain ~ top philosophical or epistemological personalities as: Edmund Husserl, Oswald Spengler, John Dewey, Lewis Althusser, Otto Neurath (Austrian sociologist member of "Vienna's circle"-for the expression and elaboration of "Neo-positivism"/with his main concept of "physicalismus"), Thomas Kuhn, Percy Bridgman, all of them also had 170-i.q. (but lesser! more or less "mental vitality" & "(final-mental) creativity" than Wittgenstein), above names as Bertrand Russell (168-i.q), Martin Heidegger (165-i.q.), Henry Bergson (160-i.q.), Jean Paul Sartre & Albert Camus (both with 155-i.q.). -In the history of philosophy & epistemology, particularly four other names have not to be forgotten: Arthur Schoppenhauer/170-i.q., David Hume & Soren Kirkegaard both with 168-i.q., and within 20th century's epistemology Paul Feyerabend/165-i.q., (above names as Herbert Spencer/165-i.q., Augumste Comte and Hegel both with 160-i.q., Leibniz/160-i.q., Ernst Mach/160-i.q., Richard Avenarious/~ 157-i.q., Spinoza, John Locke or Immanuel Kant the last three of them with 150-i.q., Karl Marx/150-i.q.,...and from the ancient world Heraclitus & Democritus both with 160-i.q. -Note: Socrates, Pythagoras & Epicurus all the three of them with 150-i.q., Aristotle/145-i.q., Plato/142-i.q. -Remark: Max Horkheimmer/of the school of Frankfurt (20th century) despite his...165-i.q! remains..."unacceptably utopian"!!!).

Ludwig Wittgenstein offers the most "analytically critical, creative & intrinsic also indefinite" philosophy of "language" & "general communication"/in art, science, e.t.c., ever written. A "critically ultimate properly-"improper" " philosophy eventually. A very interesting/as a "critical methodology" philosophy for nowadays! (to be "evenmore elaborated & "developed" " -?!...-). -M-. -P.S.: ------- For the identity of this article's author & more info (and furthermore...a lot of history's "top" scientists', artists', businessmen', e.t.c.,...i.q.s!)/about my theory, visit: FRCEC-Fischer Random Chess Email Club, -here in internet- , browse it's: Guestbook, pages of May 2008.

[Asked to publish in brief, a sort of an abstract/as regards my theory's estimations, e.t.c., from my late friend/from Pasadena-California (in 1987): myth of global chess & creator of FRC (or else chess960, or even..."quantum chess"! as I named it with his consent later in Buenos Aires (1996)) Robert James Fischer/a unique individual with ultimate non-systematic though philosophical education (on Nietzsche, e.t.c.) & i.q.-184]. "

"HIPPOLYTE TAINE...had 160-i.q. (as and the other classic genius historian: the British Arnold J. Toynbee), and his also mentally isolated "recluse" remote friend...FRIEDRICH NIETZSCHE.......:180! ......-starting point for the characterization: "universal genius"!-.

{-For instance: The music composers: a). the Austrian Wolfgang Amadeus Mozart (1756-1791) had: 187-i.q., & b). the American John Cage (within 20th century) had: 180-i.q. The chess world champion of 1972 (&...of 1992, "in real", as well) Robert James Fischer (who was and the "final thorough originator" of FRC-Fischer Random Chess or Chess960 or..."quantum chess"!...) had 184-i.q.}. MOREOVER:

A). John Stuart Mill: 190-i.q., Ludwig Feuerbach: 180-i.q., Ludwig Wittgenstein*, & Arthur Schopenhauer, & Oswald Spengler, & John Dewey, & Edmund Husserl,...& only a few others (and in epistemology): all with 170-i.q.
- {*: A world phenomenon of "mental creativity" & "mental vitality", but after the unique "myth" Friedrich Nietzsche/in these features-factors} -.

B). Bertrand Russell: 168-i.q., Herbert Spencer: 165-i.q., Henry Bergson: 160-i.q. as well as formerly Hegel (or and the composer Richard Wagner friend initially of Nietzsche),........and eventually.....

C). Jean Paul Sartre: 155-i.q. (as and Sigmund Freud),...furthermore......Karl Marx (& Vladimir Ilits Lenin, Winston Churchill, and Juan Domingo Peron, or even John Fitzgerald Kennedy, and the Yugoslav Josef Tito, -in politics!-): all the last six personalities: were first-stage geniuses with 150-i.q."

“John Mill hand an IQ of 190, Ludwig Feuerbach had IQ of 180, and Ludwig Wittgenstein, Arthur Schopenhauer, Oswald Spengler, John Dewey, and Edmund Husserl all had IQ of 170.”
