Natural Kinds

Famous quotes containing the words natural and/or kinds:

“PLAYING SHOULD BE FUN! In our great eagerness to teach our children we studiously look for “educational” toys, games with built-in lessons, books with a “message.” Often these “tools” are less interesting and stimulating than the child’s natural curiosity and playfulness. Play is by its very nature educational. And it should be pleasurable. When the fun goes out of play, most often so does the learning.”
—Joanne E. Oppenheim (20th century)

“There are only two kinds of men: the righteous who think they are sinners and the sinners who think they are righteous.”
—Blaise Pascal (1623–1662)
