The statement that human nature is egoistic is unlikely to make any headlines. But because we are naturally egoistic, we are all, without exception, prone to misusing what we know. This need not mean that we will use knowledge to commit a crime. It can express itself in very small, seemingly trifle things, like getting promoted at work when we didn’t deserve it, or taking our best friend’s loved one away from them.
The real news about egoism is not that human nature is egoistic; it is that I am an egoist. The first time we confront our own egoism is quite a sobering experience. And like any sobering, it is a giant headache.
