You need to know enough of the natural sciences so that you are not a stranger in the world. - John Searle

Finally, and perhaps most importantly, you need to acquire the skills of writing and speaking that make for candor, rigor, and clarity. You cannot think clearly if you cannot speak and write clearly.

It is apparently very congenial for some people who are professionally concerned with fictional texts to be told that all texts are really fictional anyway, and that claims that fiction differs significantly from science and philosophy can be deconstructed as a logocentric prejudice, and it seems positively exhilarating to be told that what we call "reality" is just more textuality. Furthermore, the lives of such people are made much easier than they had previously supposed, because now they don't have to worry about an author's intentions, about precisely what a text means, or about distinctions within a text between the metaphorical and the literal, or about the distinction between texts and the world because everything is just a free play of signifiers. The upper limit, and I believe the reductio ad absurdum, of this "sense of mastery" conveyed by deconstruction, is in Geoffrey Hartman's claim that the prime creative task has now passed from the literary artist to the critic.

All of our conscious states, without exception, are caused by lower level neurobiological processes in the brain, and they are realized in the brain as higher level, or system features. It's about as mysterious as the liquidity of water, right? The liquidity is not an extra juice squirted out by the H₂O molecules, it's a condition that the system is in; and just as the jar full of water can go from a liquid to solid, depending on the behavior of the molecules, so your brain can go from a state of being conscious to a state of being unconscious, depending on the behavior of the molecules. The famous mind body problem is that simple.
