As I wrote at the very beginning of this volume, I began my study of economics with reading Hicks' Value and Capital (VC). My first research results produced my first book, DKR, in Japanese. It was fourteen years after its appearance, that my first book in English was published in 1964, when I was privileged to be invited by Hicks to work with him at All Souls College. I was not entirely happy with my books; I had already started to query the appropriateness of the VC paradigm of general equilibrium (GE) to which my book belonged.

The work assigned to me at Oxford was to read the manuscript of Capital and Growth (CG), 1965, which Hicks was then writing and to comment on it. I soon realized that he too was no longer satisfied with his previous book that had long been regarded as a living classic of economics. He was groping for a new paradigm. If I am allowed to point out one title from his bibliography which he would consider as the one which would be closest to his new paradigm, I would say that he himself would single out his Capital and Time, 1973, but even this does not fully represent his new paradigm. I consider that he devoted his entire life after 1965 to the work of searching for a new paradigm (CT is one of the products of such efforts), and he would have been more satisfied from constructing a new GE model on the basis of the observations obtained in his A Market Theory of Money, 1989, published after his death.
