“For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ…Likewise also these filthy dreamers defile the flesh, despise dominion, and speak evil of dignities…But these speak evil of those things which they know not: but what they know naturally, as brute beasts they corrupt themselves. Woe unto them! For they have gone in the way of Cain, and ran greedily after the error of Balaam for reward, and perished in the gainsaying of Co-re.” (Jude 3, 4, 8, 10, 11)
Obviously the Stoics had to discard the former notion of the possible which signified an objective contingency in a non-deterministic world, and to replace it by something compatible with determinism. They did so very logically by making it a subjective category and basing it on human ignorance of the future... The meaning of "chance" underwent a change which was linked up with the new significance of the possible. It is interesting to note that the Aristotelian definition of tyche was taken over literally by the Stoics and thereby the "obscurity to human calculation" was given a new meaning.
