Famous quotes containing the words table and/or universal:
“The best thing about Sassy Seats is that grandmothers cannot figure out how they work and are in constant fear of the child’s falling. This often makes them forget to comment on other aspects of the child’s development, like why he is not yet talking or is still wearing diapers. Some grandmothers will spend an entire meal peering beneath the table and saying, “Is that thing steady?” rather than, “Have you had a doctor look at that left hand?””
—Anna Quindlen (20th century)
“Without doubt God is the universal moving force, but each being is moved according to the nature that God has given it.... He directs angels, man, animals, brute matter, in sum all created things, but each according to its nature, and man having been created free, he is freely led. This rule is truly the eternal law and in it we must believe.”
—Joseph De Maistre (1753–1821)
