Usage of The Terms "source" and "target"
With respect to the terms source and target there are two distinct traditions of usage:
- The logical and cultures and economics tradition speaks of an arrow, homomorphism, mapping, or morphism from what is typically the more complex domain or source to what is typically the less complex codomain or target, using all of these words in the sense of mathematical category theory.
- The tradition that appears more common in cognitive psychology, in literary theory, and in specializations within philosophy outside of logic, speaks of a mapping from what is typically the more familiar area of experience, the source, to what is typically the more problematic area of experience, the target.

Famous quotes containing the words usage of the, usage of, usage, terms, source and/or target:
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)

“Of course I’m a black writer.... I’m not just a black writer, but categories like black writer, woman writer and Latin American writer aren’t marginal anymore. We have to acknowledge that the thing we call “literature” is more pluralistic now, just as society ought to be. The melting pot never worked. We ought to be able to accept on equal terms everybody from the Hassidim to Walter Lippmann, from the Rastafarians to Ralph Bunche.”
—Toni Morrison (b. 1931)
“It is very difficult to be wholly joyous or wholly sad on this earth. The comic, when it is human, soon takes upon itself a face of pain; and some of our griefs ... have their source in weaknesses which must be recognized with smiling compassion as the common inheritance of us all.”
—Joseph Conrad (1857–1924)
“But this we know, the obstacle that checked
And tripped the body, shot the spirit on
Further than target ever showed or shone.”
—Robert Frost (1874–1963)
