“Study is the child of silence and mystery.”

1890s, The Path of the Law (1897)
Context: When we study law we are not studying a mystery but a well-known profession. We are studying what we shall want in order to appear before judges, or to advise people in such a way as to keep them out of court. The reason why it is a profession, why people will pay lawyers to argue for them or to advise them, is that in societies like ours the command of the public force is intrusted to the judges in certain cases, and the whole power of the state will be put forth, if necessary, to carry out their judgments and decrees. People want to know under what circumstances and how far they will run the risk of coming against what is so much stronger than themselves, and hence it becomes a business to find out when this danger is to be feared. The object of our study, then, is prediction, the prediction of the incidence of the public force through the instrumentality of the courts.

Introduction
The Philosophy of Misery (1846)
Context: Tormented by conflicting feelings, I appealed to reason; and it is reason which, amid so many dogmatic contradictions, now forces the hypothesis upon me. A priori dogmatism, applying itself to God, has proved fruitless: who knows whither the hypothesis, in its turn, will lead us?
I will explain therefore how, studying in the silence of my heart, and far from every human consideration, the mystery of social revolutions, God, the great unknown, has become for me an hypothesis, — I mean a necessary dialectical tool.

McKenna interview (1992)
Context: I love child things because there's so much mystery when you're a child. When you're a child, something as simple as a tree doesn't make sense. You see it in the distance and it looks small, but as you go closer, it seems to grow — you haven't got a handle on the rules when you're a child. We think we understand the rules when we become adults but what we really experienced is a narrowing of the imagination.

"Foreword to an Exhibit: I" (1944)
Context: Art is a mystery.
A mystery is something immeasurable.
In so far as every child and woman and man may be immeasurable, art is the mystery of every man and woman and child. In so far as a human being is an artist, skies and mountains and oceans and thunderbolts and butterflies are immeasurable; and art is every mystery of nature. Nothing measurable can be alive; nothing which is not alive can be art; nothing which cannot be art is true: and everything untrue doesn’t matter a very good God damn...
