Reflexivity, the role of history, and the case of mesmerism in early Victorian Britain.

As part of a wider argument that history is essential to psychological understanding because of the reflexive nature of psychological knowledge, this article examines the case of mesmerism in early Victorian Britain as an example of how psychological knowledge is both constructive and constructed. It is argued that the shift from "mesmerism" to "hypnotism" was a change in understanding that created a new kind of psychological experience. It is also argued that demonstrations of mesmerism, far from being self-evident facts, could be framed as evidence either for or against the central claims of mesmerism. It is concluded that the case of mesmerism in early Victorian Britain provides a further example of the need for historical understanding within Psychology.
