Substantial Part

Famous quotes containing the words substantial and/or part:

“The lore of our fathers is a fabric of sentences. In our hands it develops and changes, through more or less arbitrary and deliberate revisions and additions of our own, more or less directly occasioned by the continuing stimulation of our sense organs. It is a pale gray lore, black with fact and white with convention. But I have found no substantial reasons for concluding that there are any quite black threads in it, or any white ones.”
—Willard Van Orman Quine (b. 1908)

“Learning first occurs as a part of emotional interactions; it involves the split-second initiatives that children take as they try to engage other people, interact with them, communicate and reason with them.”
—Stanley I. Greenspan (20th century)
