Famous quotes containing the words integrity and/or constraints:
“Dreams have a poetic integrity and truth. This limbo and dust- hole of thought is presided over by a certain reason, too. Their extravagance from nature is yet within a higher nature.”
—Ralph Waldo Emerson (1803–1882)
“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)
