This article focuses on cultural reflections on American linguists. The field of linguistics as conceived by the linguists themselves was necessarily inter-disciplinary. The relevant disciplines included ethnology, pure science, history, geology and psychology. There are recognisable groupings of problems which range from characterisations of process and method to working assumptions. Characterisations of "process" which any combination of disciplines might share in any combination of ways include theses of evolutionism, historicism, uniformitarianism, instrumentalism, psychologism, diffusionism and geneticism.
