Loves or pursues or desires to obtain pain of itself, because it is pain, but circumstances occur in which toil and pain can procure him some great. To take a trivial example, which of us ever laborious physical exercise, except to obtain some advantage from it? But who find fault chooses to enjoy a pleasure one avoids a pain produces no.

Blinded by desire, that they cannot foresee blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil.
