[T]he Capgras delusion [is] a bizarre affliction that occasionally strikes human beings who have suffered brain damage. The defining mark of the Capg… - Daniel Dennett

In spite of ferocious differences of opinion about other moral issues, there seems to be something approaching consensus that it is cruel and malicious to interfere with the life-enhancing illusions of others —unless those illusions are themselves the cause of even greater ills. The disagreements come over what these greater ills might be- and this has led to the break down of the whole rationale. Keeping secrets from people for their own good can often be wise, but it takes only one person to give away a secret, and since there are disagreements about which cases warrant discretion, the result is an unsavory miasma of hypocrisy, lies, and frantic but fruitless attempts at distraction.

The term that is most often bandied about in these conflicts, typically as a term of abuse, is "reductionism." Those who yearn for skyhooks call those who eagerly settle for cranes "reductionists"... The problem is that there are both bland readings and preposterous readings of any such claim. According to the bland readings, it is possible (and desirable) to unify chemistry and physics, biology and chemistry, and, yes, even the social sciences and biology... According to the preposterous readings, reductionists want to abandon the principles, theories, vocabulary, laws of the higher-level sciences, in favor of the lowerlevel terms. A reductionist dream, on such a preposterous reading, might be to write "A Comparison of Keats and Shelley from the Molecular Point of View"... Probably nobody is a reductionist in the preposterous sense, and everybody should be a reductionist in the bland sense, so the "charge" of reductionism is too vague to merit a response.
