To those who inquire as to the purpose of mathematics, the usual answer will be that it facilitates the making of machines, the travelling from place to place, and the victory over foreign nations, whether in war or commerce. ... The reasoning faculty itself is generally conceived, by those who urge its cultivation, as merely a means for the avoidance of pitfalls and a help in the discovery of rules for the guidance of practical life.

Geometry is of much assistance in architecture, and in particular it teaches us the use of the rule and compasses, by which especially we acquire readiness in making plans for buildings in their grounds, and rightly apply the square, the level, and the plummet. By means of optics the light in buildings can be drawn from fixed quarters of the sky. Difficult questions involving symmetry are solved by means of geometrical theories and methods.
Vitruvius
How very paltry and limited the normal human intellect is, and how little lucidity there is in the human consciousness, may be judged from the fact that, despite the ephemeral brevity of human life, the uncertainty of our existence and the countless enigmas which press upon us from all sides, everyone does not continually and ceaselessly philosophize, but that only the rarest of exceptions do.
Arthur Schopenhauer
We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for humanity.

Ask yourself why totalitarian dictatorships find it necessary to pour money and effort into propaganda for their own helpless, chained, gagged slaves, who have no means of protest or defense. The answer is that even the humblest peasant or the lowest savage would rise in blind rebellion, were he to realize that he is being immolated, not to some incomprehensible noble purpose, but to plain, naked human evil.
Ayn Rand
If the subjectivist view hold true, thinking cannot be of any help in determining the desirability of any goal in itself. The acceptability of ideals, the criteria for our actions and beliefs, the leading principles of ethics and politics, all our ultimate decisions are made to depend upon factors other than reason. They are supposed to be matters of choice and predilection, and it has become meaningless to speak of truth in making practical, moral or esthetic decisions.
