...the rationale for the existence of literature lies precisely in its ability to work on issues that concern us deeply. And it does so in a way that keeps our motivation at its highest intensity. Literature is fuel for 'hot cognition.' One may presume that imaginative literature is a property that all human cultures possess and as such may provide humans with an evolutionary advantage.

...human beings are able to attend to issues longer, to think harder about them, to receive deeper impressions that last longer, if information is presented in a context of emotion--a sort of hot dressing--than if it is presented wholly without affect.
