Some philosophers and psychologists have evaluated psychological egoism against recent experimental work in social psychology. Dan Batson (1991, 2011), in particular, argues that empathy tends to induce genuinely altruistic motives in humans. However, some argue that there are egoistic explanations of the data that remain unscathed. I focus here on some recent criticisms based on the idea of self–other merging or “oneness,” primarily leveled by Robert Cialdini and his collaborators (1997). These authors argue that the putatively altruistic subjects are acting on ultimately egoistic motives because empathic feelings for someone in distress tend to cause them to blur the distinction between themselves and the other. Employing a conceptual framework for the debate, I argue that the self–other merging explanation fails to explain the empathy–helping relationship on primarily nonempirical grounds, regardless of the empirical results that Cialdini and colleagues report.
