appetitive

The rational soul is like a king; the animal soul is like an official before the king, rebuking the appetitive soul.

The faculty of the vegetative soul is the appetitive power, whose seat is in the liver.

Similarly if this fool abstains from pleasures, it is because of the weakness of his appetitive soul.

Every one of the three souls (the rational, the spirited and the appetitive) must be given its due.

The mean of the appetitive power is temperance; of the spirited power, bravery and gentleness; of the rational soul, justice.
