31Let me try to make the links to the other ideas in this chapter explicit. First, reduction of certainty attributed to perception reduces desires since you don’t actually know for sure whether the object of your desire really gives reward—or is even there. Second, if you cannot control anything, what would be the point in wanting, let alone planning, since rewards and goals cannot be attained? Seeing the insatiability of the desires should also lead to the conclusion that their total fulfillment is impossible in the long run, so the desires should be dropped as futile; seeing desires as evolutionary obsessions means realising they can even be bad for you. Self-needs, in particular self-evaluation, can be considered as forms of desires in this context, and the same ideas apply to them.
