Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit. Aristotle
Love is the word used to label the sexual excitement of the young, the habituation of the middle-aged, and the mutual dependence of the old. John Ciardi
It is exceedingly improbable that the identical action of the corresponding parts of the two retina is the result of a certain habituation, or of the influence of the mind. Johannes P. Muller
