„One of the most important axioms is, that as the quantity of any commodity, for instance, plain food, which a man has to consume, increases, so the utility or benefit derived from the last portion used decreases in degree. The decrease in enjoyment between the beginning and the end of a meal may be taken as an example. And I assume that on an average, the ratio of utility is some continuous mathematical function of the quantity of commodity. This law of utility has, in fact, always been assumed by political economists under the more complex form and name of the Law of Supply and Demand. But once fairly stated in its simple form, it opens up the whole of the subject.“

„I approached the problem of utility measurement in 1923 during a stay in Paris. There were three objects I had in view :
:(I) To point out the choice axioms that are implied when we think of utility as a quantity, and to define utility in a rigorous way by starting from a set of such axioms;
:(II) To develop a method of measuring utility statistically;
:(III) To apply the method to actual data.
The results of my study along these lines are contained in a paper “Sur un Problème d’Économic Pure”, published in the Series Norsk Matematisk Forenings Skrifter, Serie I, Nr 16, 1926. In this paper, the axiomatics are worked out so far as the static utility concept is concerned. The method of measurement developed is the method of isoquants, which is also outlined in Section 4 below. The statistical data to which the method was applied were sales and price statistics collected by the “Union des Coopérateurs Parisien”. From these data I constructed what I believe can be considered the marginal utility curve of money for the “average” member of the group of people forming the customers of the union. To my knowledge, this is the first marginal utility curve of money ever published.“

„There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.“
