Famous quotes containing the words integrity and/or constraints:
“The genius of American culture and its integrity comes from fidelity to the light. Plain as day, we say. Happy as the day is long. Early to bed, early to rise. American virtues are daylight virtues: honesty, integrity, plain speech. We say yes when we mean yes and no when we mean no, and all else comes from the evil one. America presumes innocence and even the right to happiness.”
—Richard Rodriguez (b. 1944)
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
