Imagination is not an empirical or superadded power of consciousness, it is the whole of consciousness as it realizes its freedom.
~ Jean-Paul Sartre
Designs fulfilling a purpose are like tools. They are neither decorative
objects nor works of art.
~ Dieter Rams
Economic theory as derived from Adam Smith assumes first that homo economicus acts with perfect optimality on complete information, and second that when many of the species homo economicus do that, their actions add up to the best possible outcome for everybody. Neither of these assumptions stands up long against the evidence.
~ Donella Meadows
