citation - operations more akin to pleasures b/c conjoined to them

CITATION: - 34.1 - are all pleasures evil? And another reason can be taken form the part of hte operation, of which some are good good, and some bad.For operations are more akin to pleasures, because they are conjoined to them, as concupiscence, which precedes them in time. Whence, since the desires of good operations are good, but evil ones are bad; so much more are the pleasures of good operations good, but of evil ones, evil.
