[The notion of equilibrium] is a notion which can be employed usefully in varying degrees of looseness. It is an absolutely indispensable part of the toolbag of the economist and one which he can often contribute usefully to other sciences which are occasionally apt to get lost in the trackless exfoliations of purely dynamic systems.
Equilibrium is a figment of the human imagination.
The equilibrium model describes systems which, in moving to an equilibrium point, typically lose organization, and then tend to hold that minimum level within relatively narrow conditions of disturbance.
The equilibrium between supply and demand is achieved only through a reaction against the upsetting of the equilibrium.
To dispose a soul to action we must upset its equilibrium.
Good and evil grow up together and are bound in an equilibrium that cannot be sundered. The most we can do is try to tilt the equilibrium toward the good.
