An Exposition of the Orthodox Faith 40
An Exposition of the Orthodox Faith by St. John of Damascus (translated by E.W. Watson and L. Pullan, 1899)
1 BOOK II — CHAPTER 26: Concerning Events.
2 Of events, some are in our hands, others are not. Those then are in our hands which we are free to do or not to do at our will, that is all actions that are done voluntarily, and in a word, all that are followed by blame or praise and depend on motive and law. Strictly all mental and deliberative acts are in our hands. Now deliberation is concerned with equal possibilities: and an 'equal possibility' is an action that is itself within our power and its opposite, and our mind makes choice of the alternatives, and this is the origin of action.
3 Note, however, that while the choice of what is to be done is ever in our power, the action itself often is prevented by some dispensation of the divine Providence.
