I told Husserl I had been working on an exposition of the natural attitude as a preliminary to an exposition of the phenomenological reduction. He said that he thought that everyone would have to undertake such a work, quite independently, and with due regard to his own personal difficulties — a detailed, written work. My exposition, if intended for publication, will have to be much more elementary than if it were written just for myself. For America he thought that an Anknüpfung 〈exposition relating to〉 on (1) James's Radical Empiricism, (2) other elements in James's thought, and (3) J. S. Mill, might be helpful.
