In this science the illustrations and examples are not confined in their effect merely to the practice they afford in the analytical art, but [...] they also store the mind with independent geometrical and physical knowledge. Besides, it should be considered, that the only effectual method of impressing abstract formulae and rules upon the memory, and, indeed, of making them fully and clearly apprehended by the understanding, is by examples of their practical application.

The difficulty in our education up till now lies, for the most part, in the fact that knowledge did not refine itself into will, to application of itself, to pure practice. The realists felt the need and supplied it, though in a most miserable way, by cultivating idea-less and fettered "practical men." Most college students are living examples of this sad turn of events. Trained in the most excellent manner, they go on training; drilled they continue drilling.
Max Stirner
There cannot be a greater mistake than that of looking superciliously upon the practical applications of science. The life and soul of science is its practical application; and just as the great advances in mathematics have been made through the desire of discovering the solution of problems which were of a highly practical kind in mathematical science, so in physical science many of the greatest advances that have been made from the beginning of the world to the present time have been made in earnest desire to turn the knowledge of the properties of matter to some purpose useful to mankind.

Lord Kelvin
The rules that obtain among themselves [a people] appear to them self-evident and self-justifying. This all but universal illusion is one of the examples of the magical influence of custom, which is not only, as the proverb says, a second nature, but is continually mistaken for the first. The effect of custom, in preventing any misgiving respecting the rules of conduct which mankind impose on one another, is all the more complete because the subject is one on which it is not generally considered necessary that reasons should be given, either by one person to others, or by each to himself.
John Stuart Mill
To my knowledge significant progress has never been born of competition. ... In science, being 'better' than others is of little practical value. Examples of how absurd the idea of scientific competition is are abundant.
