“The bitterest tragic element in life to be derived from an intellectual source is the belief in a brute Fate or Destiny.”

Presidential Address to All India Muslim League's Session on March 22, 1940
Context: It is extremely difficult to appreciate why our Hindu friends fail to understand the real nature of Islam and Hinduism. They are not religions in the strict sense of the word, but are, in fact, different and distinct social orders, and it is a dream that the Hindus and Muslims can ever evolve a common nationality, and this misconception of one Indian nation has troubles and will lead India to destruction if we fail to revise our notions in time. The Hindus and Muslims belong to two different religious philosophies, social customs, litterateurs. They neither intermarry nor interdine together and, indeed, they belong to two different civilizations which are based mainly on conflicting ideas and conceptions. Their aspect on life and of life are different. It is quite clear that Hindus and Mussalmans (Muslims) derive their inspiration from different sources of history. They have different epics, different heroes, and different episodes. Very often the hero of one is a foe of the other and, likewise, their victories and defeats overlap. To yoke together two such nations under a single state, one as a numerical minority and the other as a majority, must lead to growing discontent and final destruction of any fabric that may be so built for the government of such a state.

The facts and fancies of Mr. Darwin (1862)
Context: It is a more rational belief that man may become a brute than that a brute may become a man; and it is an easier faith that plants and animals may dwindle down into an elemental atom, than that this atom should embrace in its organization, and evolve, all the noble forms of vegetable, animal, and intellectual life.

The Artful Universe (1995)
Context: Ancient belief in a cosmos composed of spheres, producing music as angels guided them through the heavens, was still fluorishing in Elizabethan times.... There is a good deal more to Pythagorean musical theory than celestial harmony. Besides the music of the celestial spheres (musica mundana), two other varieties of music were distinguished: the sound of instruments...(musica instrumentalis), and the continuous unheard music that emanated from the human body (musica humana), which arises from a resonance between the body and the soul.... In the medieval world, the status of music is revealed by its position within the Quadrivium—the fourfold curriculum—alongside arithmetic, geometry, and astronomy. Medieval students... believed all forms of harmony to derive from a common source. Before Boethius' studies in the ninth century, the idea of musical harmony was not considered independently of wider matters of celestial or ethical harmony.<!-- Ch. 5, pp. 201-202
