 But Bradley does not stop at character formation, claiming that human nature itself is evolving. He rejects the traditional view that one’s essential human nature remains unchanged even though there will be some differences in people that are only historical accidents. The contrary position is a metaphysical doctrine, often called historicity, which claims that human beings are self-making within the limits of their natural and social contexts. There is a dialectical relationship between these aspects of the human condition: we are not only constrained by natural and social contexts but can often alter natural conditions and social arrangements, thereby influencing how they impact on our choices. For example, my ability to think certain things possible will be a function of my conception of the social institutions of my society. If marriages are defined as being between a male and a female, I may not even contemplate the possibility of being in a same-sex marriage leave alone feel free to act on the idea. Yet, change is possible because human beings have the ability to represent states of affairs that do not exist. In its most familiar form this happens when you plan tomorrow’s dinner.
