There is a mortifying experience in particular, which does not fail to wreak itself also in the general history; I mean "the foolish face of praise," the forced smile which we put on in company where we do not feel at ease, in answer to conversation which does not interest us. The muscles, not spontaneously moved but moved, by a low usurping wilfulness, grow tight about the outline of the face, with the most disagreeable sensation.
The eighth commandment reads, "Thou shalt not steal." It does not read, "Thou shalt not steal from the rich man." It does not read, "Thou shalt not steal from the poor man." It reads simply and plainly, "Thou shalt not steal."
Common sense invents and constructs no less than its own field than science does in its domain. It is, however, in the nature of common sense not to be aware of this situation.
I am not a positivist. Positivism states that what cannot be observed does not exist. This conception is scientifically indefensible, for it is impossible to make valid affirmations of what people 'can' or 'cannot' observe. One would have to say 'only what we observe exists,' which is obviously false.
One does not concern oneself with the expressions, but rather with life. You are looking at life through the wrong end of the telescope when you look at the expressions of life.
