A Dream (n.) lets a man make the clearest judgements and the most saintly decisions in the middle of the grossest contradictions — because, even dreaming, he can only desire what he looks upon as good.
Imagination (n.) takes flight in dreams through lack of orientation; its unbridled extravagance comes from the absence of critical reflection and of other people to talk to.
Responsibility (n.) reaches into sleep only indirectly: we are not answerable for dream-wishes, yet we have a duty to cleanse our minds morally, especially before going to sleep.
Virtue (n.) goes to bed with us: the virtuous man resists temptation even in his dreams, while the sinner finds there the same images he had before his eyes all day.
