“Popular wisdom recognizes that care killed the cat because when the cat cares too much, it does not fall limply from the branch of a tree. Nothing is stronger than a certain give, or springy absence of rigidity, and this is certainly why evolution seems to favor the mammals more than the crustaceans—sensitive flesh around bone rather than insensitive bone around flesh. Without its resilient ease and looseness, the cat would certainly not have its nine lives.”

— Alan Watts, The Two Hands of God
