Famous quotes containing the word material:
“I do not deny the existence of material substance merely because I have no notion of it, but because the notion of it is inconsistent, or in other words, because it is repugnant that there should be a notion of it.”
—George Berkeley (1685–1753)
“Trying to love your children equally is a losing battle. Your children’s scorecards will never match your own. No matter how meticulously you measure and mete out your love and attention, and material gifts, it will never feel truly equal to your children. . . . Your children will need different things at different times, and true equality won’t really serve their different needs very well, anyway.”
—Marianne E. Neifert (20th century)
“When science is learned in love, and its powers are wielded by love, they will appear the supplements and continuations of the material creation.”
—Ralph Waldo Emerson (1803–1882)
