Genealogy as Critique

Genealogy as Critique

Genealogy as critique is explaining an idea by showing where it came from, who built it and whom it served. It is a real historical method with real explanatory force, and Friedrich Nietzsche's On the Genealogy of Morality in 1887 is the founding case, with Michel Foucault its most influential modern practitioner. It is not evidence about whether the idea is true, and treating it as such is the genetic fallacy. The rule this publication works to is that a verdict by motive is not a refutation, and a reader has to be able to tell the two apart.

What it is

The method takes an idea that presents itself as timeless and shows it having been made: at a date, by identifiable people, in circumstances that gave them reasons. Nietzsche applied it to moral concepts. Foucault applied it to madness, punishment and sexuality, and the phrase that names the approach is the title of Colin Koopman's 2013 study of him.

What the method is genuinely good at is dissolving the appearance of necessity. An idea that looks like a discovery about the world turns out to have a history, and the history usually contains choices that could have gone differently.

What it cannot do is settle the truth of the idea. Showing that a heritage whisky label was invented by an agency in 1998 tells you a great deal about the marketing and nothing at all about how the whisky tastes. The origin of a claim and the evidence for a claim are separate questions, and the genetic fallacy is the name for merging them.

In effect

In practice the risk is not that a writer states the fallacy outright. It is asymmetry, and asymmetry is only visible when you ask what test each side is put to.

A history of intelligence testing supplies the case this publication has looked at closely. Hereditarian claims in that book are explained by tracing them to the people who made them and the inequalities those people defended, which is genealogy and is done well. Progressive alternatives in the same book are assessed on evidence. The notes are sound on both sides. The pattern shows only in the question of which standard each side meets, and it is an observable feature of the text rather than an inference about anyone's motives.

The failure mode at the far end is the unfalsifiable frame, in which every counterexample is itself explained by motive, and the account becomes unable to be wrong.

Used well, the method is a prompt rather than a verdict: here is where this came from, now go and check whether it is true.

What it does not say

It does not refute anything. An idea with a discreditable origin can be correct, and an idea with an honourable one can be false.

It does not say motives are irrelevant. Knowing who funded a body of research and what they wanted from it is legitimate and often necessary context for deciding how much scrutiny to apply.

It does not license inferring motive from a pattern in a text. Where this publication records an asymmetry, it records what the text does and stops there.

And it is not a finding. It is a method from philosophy and history, and nothing about it was tested.
