Again, this is an ideological distortion. Systems are rational, systems of organization, ideational systems, but individuals are not inherently rational. We cannot hypostatize a sociocultural phenomenon as innate. I have presented research on this channel before showing that, for the most part, individuals are nonrational, and that they must learn to be rational, and even scientist generally operate nonrationally or irrationally. And while we may describe behavior in certain useful terms, we must be careful not to confuse the mode of description and explanation with the object being described and explained, or else we project into the object the ideas we use to understand the object.
Individual rationality is just such a false reification.
Individuals are not innately rational anymore than they are innately racist. The point is that neither one of the perspectives presented here, either condemning Weber for alleged racism or defending Weber against racist charges to keep Weber's system pure, take off from a sufficiently realistic basis. I think this is the more important lesson to be learned from this exchange.
