Famous quotes containing the word differences:
“When was it that the particles became
The whole man, that tempers and beliefs became
Temper and belief and that differences lost
Difference and were one? It had to be
In the presence of a solitude of the self....”
—Wallace Stevens (1879–1955)
“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts. The bond for normal twins, whether they are identical or fraternal, is based on how they, as individuals who are keenly aware of the differences between them, learn to relate to one another.”
—Pamela Patrick Novotny (20th century)
