The thing about Foucault that makes his work meaningful to me is how he hit the nail on the head about how power is changing and continuing to change in society. It has become diffuse and self-perpetuating. It lacks a direct, physical force but still coerces. It is no longer socially acceptable or legal for men to withhold food from their wives, but women suffer from eating disorders in large numbers. Slavery is no longer legal in the US, but a large % of black people are incarcerated and forced to do free labor. The internet has given us access to an enormous amount of information, and yet we are addicted to social media and controlled by algorithms.

I think the same can be said about Freud, Marx, and Nietzsche. A lot of their work does not hold up, but within their work are gems of insight that have stood the test of time. Just because they do not adhere to the methodologies of analytical philosophy does not mean that they haven't produced important thought.
