“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
“As in digging for precious metals in the mines, much earthy rubbish has first to be troublesomely handled and thrown out; so, in digging in one’s soul for the fine gold of genius, much dullness and common-place is first brought to light.”
—Herman Melville (1819–1891)
