For every sort of pleasure is never anything more than the quietive of some need or longing; and that pleasure should come to an end as soon as the need ceases, is no more a subject of complaint than that a man cannot go on eating after he has had his dinner, or fall asleep again after a good night's rest.

Here knowledge, turned away from the individual and vain to the whole and genuine, ceases to be a motive for the will and becomes a means of stilling it; the intellect is transformed from a motive into a quietive, and brings him who gives himself up to the All safely out from the storm of the passions into the peace of deliverance from existence.
