'Knowledge, without common sense,' says Lee, is 'folly; without method, it is waste; without kindness, it is fanaticism; without religion, it is death.' But with common sense, it is wisdom with method, it is power; with charity, it is beneficence; with religion, it is virtue, and life, and peace.
My life isn't theories and formulas. It's part instinct, part common sense. Logic is as good a word as any, and I've absorbed what logic I have from everything and everyone . . . from my mother, from training as a ballet dancer, from magazine, from the laws of life and health and nature.
Now in creative thought common sense is a bad master. Its sole criterion for judgement is that the new ideas shall look like the old ones. In other words it can only work by suppressing originality.
