According to Rachels, a weak argument for the case of Phycological Egoism is that no matter what choice we make we are choosing what we most want. Continuing with this argument, if we do what we most want to do then we are in fact acting egoistically. Rachels gave the example of a person who chose to forgo a vacation in favor of helping a friend. While the person would have enjoyed the vacation more than helping his friend, he decide to help his friend because that is what he wanted to do. Therefore it could be said he was acting egoistically. However, Rachels attacks this way of thinking. He went on to explain that by choosing to stay and help his friend, the person was doing what they most wanted to do. The action was not out of egoism
