> As with Dada, altruism doesn't survive intellectual evaluation.

Sure and I'm not as interested in discussing the philosophical ideal of altruism. My interest in charitable work, as I suspect many interested in EA feel, stems from trying to do the greatest good with my limited allocation of resources, be that money, time, knowledge, manual labor, or otherwise. In that regard I'm unconcerned about the usual moral philosophical questions about motive and goodness.
