"Aristotle's opinion... that comets were nothing else than sublunary vapors or airy meteors... prevailed so far amongst the Greeks, that this sublimest part of astronomy lay altogether neglected; since none could think it worthwhile to observe, and to give an account of the wandering and uncertain paths of vapours floating in the Ether."

Mutability is the badge of infirmity. It is seldom that a man continues to wish and design the same thing two days alike. Now he is for marrying; and now a mistress is preferred to a wife. Now he is ambitious and aspiring; presently the meanest servant is not more humble than he. This hour he squanders his money away; the next he turns miser. Sometimes he is frugal and serious; at other times profuse, airy, and gay.
