involuntarily?

HIPPIAS: That appears to be the truth.

SOCRATES: And what would you say of any other bodily exercise--is not he
who is better made able to do both that which is strong and that which is
weak--that which is fair and that which is foul?--so that when he does bad
actions with the body, he who is better made does them voluntarily, and he
who is worse made does them involuntarily.

HIPPIAS: Yes, that appears to be true about strength.

SOCRATES: And what do you say about grace, Hippias? Is not he who is
better made able to assume evil and disgraceful figures and postures
voluntarily, as he who is worse made assumes them involuntarily?

HIPPIAS: True.

SOCRATES: Then voluntary ungracefulness comes from excellence of the
bodily frame, and involuntary from the defect of the bodily frame?

HIPPIAS: True.

SOCRATES: And what would you say of an unmusical voice; would you prefer
the voice which is voluntarily or involuntarily out of tune?

HIPPIAS: That which is voluntarily out of tune.

SOCRATES: The involuntary is the worse of the two?
