Norm Quotes (5 quotes)

Usus quem penes arbitrium est et jus norma loquendi.
Usage, in which lies the decision, the law, and the norm of speech.
Horace
From 'Epistola ad Pisones', known as 'De Arte Poetica', lines 71-72. The Works of Horace (1893), 304. Another translation gives, “If usage wills, within whose power are the laws and rules of speech.” A looser interpretation explains, “Words, like other human things, have their day, and pass and change.” A related comment would be, “Use is the tyrant of languages.” In context, Horace is meaning the usage of refined, cultured, educated class in their writings and speech as masters of the language.

Although species may be discrete, they have no immutable essence. Variation is the raw material of evolutionary change. It represents the fundamental reality of nature, not an accident about a created norm. Variation is primary; essences are illusory. Species must be defined as ranges of irreducible variation.

My visceral perception of brotherhood harmonizes with our best modern biological knowledge ... Many people think (or fear) that equality of human races represents a hope of liberal sentimentality probably squashed by the hard realities of history. They are wrong. This essay can be summarized in a single phrase, a motto if you will: Human equality is a contingent fact of history. Equality is not true by definition; it is neither an ethical principle (though equal treatment may be) nor a statement about norms of social action. It just worked out that way. A hundred different and plausible scenarios for human history would have yielded other results (and moral dilemmas of enormous magnitude). They didn’t happen.

The consideration of mathematics is at the base of knowledge of the mind as it is at the base of the natural sciences, and for the same reason: the free and fertile work of thought dates from that epoch when mathematics brought to man the true norm of truth.
As translated in James Byrnie Shaw, Lectures on the Philosophy of Mathematics (1918), 193. From Léon Brunschvicg, Les Étapes de La Philosophie Mathématique (1912), 577, “La considération de la mathématique est à la base de la connaissance de l’esprit comme elle est à la base des sciences de la nature, et pour une même raison: l’œuvre libre et féconde de la pensée date de l’époque où la mathématique vint apporter à l’homme la norme véritable de la vérité.”

When people talk about “the sanctity of the individual” they mean “the sanctity of the statistical norm”.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
