Quote #10
Of action, then, choice is the origin—that from which the motion arises but not that for the sake of which one moves; and of choice, the origin is one's longing and the reasoning that indicates what it is for the sake of which one acts. Hence there cannot be choice either in the absence of intellect and thinking or in the absence of moral characteristic, for there cannot be acting well or its contrary in action in the absence of thinking and character. (6.2.1139a31-36)
Some might argue that we can act perfectly well without thinking. Aristotle would clearly disagree. In this chain of command, we can see that choice is rooted in both thought and virtue. We sift through opinions about a course of action when we deliberate about how best to reach the desired end—which should be shaped by virtuous longing.
"Snap judgments" would not, then, be considered the product of proper choice. By further defining how choice works, Aristotle's also rapidly narrowing our perception of what kinds of actions are voluntary…since choice is a crucial component of intentional behavior.
