Here are two excellent essays, each taking opposing stances on how to answer questions centring on nature and normativity, alongside the roles of sciences and humanities in understanding reality. Both are admirably lucid and make a good case for their competing methodologies: firstly, an unashamed defence of ‘scientism'; secondly, the demand to take the standpoint of practical reasoning seriously.
An excerpt from each, beginning with Alex Rosenberg’s ‘The Disenchanted Naturalist’s Guide To Reality’:
What science has discovered about reality can’t be packaged into whodunit narratives about motives and actions. The human mind is the product of a long process of selection for being able to scope out other people’s motives. The way nature solved the problem of endowing us with that ability is by making us conspiracy theorists—we see motives everywhere in nature, and our curiosity is only satisfied when we learn the “meaning” of things—whose purposes they serve. The fundamental laws of nature are mostly timeless mathematical truths that work just as well backwards as forward, and in which purposes have no role. That’s why most people have a hard time wrapping their minds around physics or chemistry. It’s why science writers are always advised to get the science across to people by telling a story, and why it never really works. Science’s laws and theories just don’t come in stories with surprising starts, exciting middles and satisfying dénouements. That makes them hard to remember and hard to understand. Our demand for plotted narratives is the greatest obstacle to getting a grip on reality. It’s also what greases the skids down the slippery slope to religion’s “greatest story ever told.” Scientism helps us see how mistaken the demand for stories instead of theories really is.
From Robert Pippin’s ‘Normative and Natural’:
Normative questions, I mean, are irreducibly “first-personal” questions, and these questions are practically unavoidable and necessarily linked to the social practice of giving and demanding reasons for what we do, especially when something someone does affects, changes or limits what another would otherwise have been able to do. By irreducibly first-personal, I mean that whenever anyone faces a normative question (which is the stance from which normative issues are issues) – what ought to be believed or what ought to be done – no third-personal fact about “why one as a matter of fact has come to prefer this or that” can be relevant to what I must decide, unless (for good practical reasons) I count it as a relevant practical reason in the justification of what I decide. Knowing something about evolutionary psychology might contribute something to understanding the revenge culture in which Orestes finds himself in Aeschylus’s Oresteia, and so why he feels pulled both to avenge his father’s murder by his mother Clytemnestra, and also feels horrified at the prospect of killing his mother in cold blood. But none of that can be, would be, at all helpful to Orestes or anyone in his position. Knowing something about the evolutionary benefits of altruistic behavior might give us an interesting perspective on some particular altruistic act, but for the agent, first-personally, the question I must decide is whether I ought to act altruistically and if so why. I cannot simply stand by, as it were, and “wait” to see what my highly and complexly evolved neuro-biological system will do. “It” doesn’t decide anything; I do, and this for reasons I must find compelling, or at least ones that outweigh countervailing considerations. It is in this sense that the first-personal perspective is strictly unavoidable. I am not a passenger on a vessel pulled hither and yon by impulses and desires; I have to steer.
