ABSTRACT
In this volume an attempt is made to discuss the theory of economic growth with a minimum of mathematical analysis. In the main text no differential or integral calculus is employed; such mathematical techniques are used (and even so very sparingly) only in footnotes and appendices which the general reader may avoid. Nevertheless there remain certain measurements and manipulations of rates of growth which must be employed in the main text. These processes could be most readily and easily expressed in terms of the differential calculus; but it is the purpose of this introductory note to explain them without any explicit use of the differential calculus, so that the non-mathematical reader will be in a position to read the text of this work without undue difficulty.
