In a strict usage the same symbol should never represent the act of sincerely asserting something and the content of what is asserted. For the symbolic distinction between the two, Frege has introduced the 'signpost' symbol. ... \vdash p is to signify the actual assertion of p, while the bare symbol p must henceforth be used only as part of a sentence. ... It should be clear from the modality of a sentence whether it is a question, a command, an invective, a complaint or an allegation of fact.

Whether a law be void for its repugnancy to the Constitution, is, at all times, a question of much delicacy, which out seldom, if ever, to be decided in the affirmative, in doubtful case. ... But it is not on slight implication and vague conjecture that the legislature is to be pronounced to have transcended its powers, and its acts to be considered as void. The opposition between the Constitution and the law should be such that the judge feels a clear and strong conviction of their incompatibility with each other.
John Marshall
It cannot be too frequently emphasized that the behavior of any animal must depend upon on the nature of the stimulus which it meets, its anatomic and physiologic capacities, and its background of previous experience. Unless it has been conditioned by previous experience, an animal should respond identically to identical stimuli, whether they emanate from some part of its own body, from another individual of the same sex, or from an individual of the opposite sex.
Alfred Kinsey
The nude gains its enduring value from the fact that it reconciles several contrary states. It takes the most sensual and immediately interesting object, the human body, and puts it out of reach of time and desire; it takes the most purely rational concept of which mankind is capable, mathematical order, and makes it a delight to the senses; and it takes the vague fears of the unknown and sweetens them by showing that the gods are like men and may be worshiped for their life-giving beauty rather than their death-dealing powers.
Kenneth Clark
Survival, with honor, that outmoded and all-important word, is as difficult as ever and as all-important to a writer. Those who do not last are always more beloved since no one has to see them in their long, dull, unrelenting, no-quarter-given-and-no-quarter-received, fights that they make to do something as they believe it should be done before they die. Those who die or quit early and easy and with every good reason are preferred because they are understandable and human. Failure and well-disguised cowardice are more human and more beloved.
Ernest Hemingway
The difficulty in understanding the Russian is that we do not take cognizance of the fact that he is not a European, but an Asiatic, and therefore thinks deviously. We can no more understand a Russian than a Chinaman or a Japanese, and from what I have seen of them, I have no particular desire to understand them, except to ascertain how much lead or iron it takes to kill them. In addition to his other Asiatic characteristics, the Russian have no regard for human life and is an all out son of bitch, barbarian, and chronic drunk.
George S. Patton
