Variant: Mayor aims of general theory:
(1) There is a general tendency toward integration in the various sciences, natural and social.
(2) Such integration seems to be centered in a general theory of systems.
(3) Such theory may be an important means for aiming at exact theory in the nonphysical fields of science.
(4) Developing unifying principles running "vertically" through the universe of the individual sciences, this theory brings us nearer the goal of the unity of science.
(5) This can lead to a much-needed integration in scientific education.

“The progress of the sciences toward theories of fundamental unity, cosmic symmetry (as in the unified field theory) — how do such theories differ, in the end, from that unity which Plato called “unspeakable” and “indiscribable,” the holistic knowledge shared by so many peoples of the earth, Christians included, before the advent of the industrial revolution made new barbarians of the peoples of the West?”
The Snow Leopard (1978)
Context: The progress of the sciences toward theories of fundamental unity, cosmic symmetry (as in the unified field theory) — how do such theories differ, in the end, from that unity which Plato called “unspeakable” and “indiscribable,” the holistic knowledge shared by so many peoples of the earth, Christians included, before the advent of the industrial revolution made new barbarians of the peoples of the West? In the United States, before spiritualist foolishness at the end of the last century confused mysticism with “the occult” and tarnished both, William James wrote a master work of metaphysics; Emerson spoke of “the wise silence, the universal beauty, to which every part and particle is equally related, the eternal One . . .”; Melville referred to “that profound silence, that only voice of God”; Walt Whitman celebrated the most ancient secret, that no God could be found “more divine than yourself.” And then, almost everywhere, a clear and subtle illumination that lent magnificence to life and peace to death was overwhelmed in the hard glare of technology. Yet that light is always present, like the stars of noon. Man must perceive it if he is to transcend his fear of meaningless, for no amount of “progress” can take its place. We have outsmarted ourselves, like greedy monkeys, and now we are full of dread.

(...) De nouvelles connaissances conduisent à reconnaître dans la théorie de l'évolution plus qu'une hypothèse. Il est en effet remarquable que cette théorie se soit progressivement imposée à l'esprit des chercheurs, à la suite d'une série de découvertes faites dans diverses disciplines du savoir. La convergence, nullement recherchée ou provoquée, des résultats de travaux menés indépendamment les uns des autres, constitue par elle même un argument significatif en faveur de cette théorie.
early news reports mistranslated the French phrase plus qu'une hypothèse as "more than one hypothesis". http://www.cartage.org.lb/en/themes/sciences/LifeScience/PhysicalAnthropology/EvolutionFact/Evolution/Evolution.htm

Context: Faced by the dire nihilism of our time, we need a greater honesty... The Western search for unifying truth did not come to an end with Christianity, any more than with the physical theories of forty years ago.
