for no one observes in himself a change from passion to judgement, and from judgement back to passion; nor does anyone cease from loving when he reflects that it would be well to break the affair off and strive with all his might against it; nor again, does he put on one side reflection and judgement, when he gives way and is overcome by desire.

Context

“For desire and fear and anger and the like they consider only depraved opinions and judgements, not in one portion of the soul only but in all its leading principles, inclinations and yieldings, and assents and impulses, and generally speaking in its energies soon changed, like the sallies of children, whose fury and excessive violence is unstable by reason of their weakness. But these views are, in the first place, contrary to evidence and observation; for no one observes in himself a change from passion to judgement, and from judgement back to passion; nor does anyone cease from loving when he reflects that it would be well to break the affair off and strive with all his might against it; nor again, does he put on one side reflection and judgement, when he gives way and is overcome by desire. Moreover, when he resists passion by reason, he does not escape passion altogether; nor again, when he is mastered by passion does he fail to discern his fault through reason: so that neither by passion does he abolish reason, nor does he by reason get rid of passion, but is tossed about to and fro alternately between passion and reason.” source
