Notice also that children and irrational creatures perform voluntary actions, but these do not involve the exercise of choice: further, all our actions that are done in anger and without previous deliberation are voluntary actions, but do not in the least involve free choice Nemes., ch. 33.. Also, if a friend suddenly appears on the scene, or if one unexpectedly lights on a treasure, so far as we are concerned it is quite voluntary, but there is no question of choice in the matter. For all these things are voluntary, because we desire pleasure from them, but they do not by any means imply choice, because they are not the result of deliberation. And deliberation must assuredly precede choice, as we have said above.
