The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work.

Criticism is often not a science; it is a craft, requiring more good health than wit, more hard work than talent, more habit than native genius. In the hands of a man who has read widely but lacks judgment, applied to certain subjects it can corrupt both its readers and the writer himself.
Jean de La Bruyère
To suppose such a thing possible as a society, in which men, who are able and willing to work, cannot support their families, and ought, with a great part of the women, to be compelled to lead a life of celibacy, for fear of having children to be starved to suppose such a thing possible is monstrous.
William Cobbett
The return from your work must be the satisfaction which that work brings you and the worlds need of that work. With this, life is heaven, or as near heaven as you can get. Without this with work which you despise, which bores you, and which the world does not need this life is hell.
W. E. B. Du Bois
After years of work in both areas of study, I concluded that the social sciences were different, in many important ways, from the natural sciences, but that the same scientific methods were applicable in both areas, and, indeed, that no very useful work could be done in either area except by scientific methods.
Carroll Quigley
We seldom know what we're hearing when we hear something for the first time, but one thing is certain: we hear it as we will never hear it again. We return to the moment to experience it, I suppose, but we can never really find it, only its memory, the faintest imprint of what it really was, what it meant.
