citaat

There are no separate systems. Where to draw a boundary depends on the questions we want to ask.

Donella H. Meadows

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.

Aristoteles
