Note BB — PREFACE (continued 2)

Precisely the same misconception of Hamilton’s position occurs in Professor De Morgan’s paper in the Cambridge Transactions, to which we have previously referred. He speaks (p. 13) of the “notion, which runs through many writers, from Descartes to Hamilton, that the mind must be big enough to hold all it can conceive.” This notion is certainly not maintained by Hamilton, nor yet by Descartes in the paragraph quoted by Mr. De Morgan; nor, as far as we are aware, in any other part of his works.
