Possibility is the essence of all things in life, except skiing through a revolving door.
Possibility is of such critical importance to human existence that one might say: 'I can, therefore I am.
Possibility is constitutive of entities in that I cannot be aware of an entity as such unless I am aware of alternative possibilities, and these depend on a wider whole.
Possibility is dangerous when not limited. The self becomes lost in possibility when it has lost the power to obey, to submit to the necessity in one's life, to what may be called one's limitations.
Possibility is, for God, impossible... only the impossible is possible for God, because the possible he has given over to the mechanics of matter and the autonomy of his creatures.
Possibility is an abundance of thoughts and ideas, which, when held out too long in the abstract, becomes as unpleasant as the anxiety suffered by a cow that is not milked on time.
Possibility is a remedy for despair just as water is the remedy to someone who has fainted. Just as when someone faints we call for 'water, water, water', when one is in despair we must call for 'possibility, possibility, possibility', for without possibility a person is unable to breathe, but with it, a person in despair breathes again, he revives again.
