„Two important features in the modern development of economics are the application of mathematics to abstract economic reasoning... and the attempt at placing economics on a numerical and experimental basis by an intensive study of economic statistics.
Both these developments have a common characteristic: they emphasize the quantitative character of economics. This quantitative movement in our estimation is one of the most promising developments in modern economics. We also consider it important that the two aspects of the quantitative method referred to should be furthered, developed, and studied jointly as two integrating parts of economics.
We therefore venture to propose the establishment of an international periodical devoted to the advancement of the quantitative study of economic phenomena, and especially to the development of a closer relation between pure economics and economic statistics.
We believe that the scope of the new journal would be happily suggested if it is called "Oekonometrika". Accordingly, the quantitative study of economic phenomena here considered may be termed econometrics.“

„We regard as "scientific" a method based on deep analysis of facts, theories, and views, presupposing unprejudiced, unfearing open discussion and conclusions.“

—  Andrei Sakharov Soviet nuclear physicist and human rights activist 1921 - 1989
Context: We regard as "scientific" a method based on deep analysis of facts, theories, and views, presupposing unprejudiced, unfearing open discussion and conclusions. The complexity and diversity of all the phenomena of modern life, the great possibilities and dangers linked with the scientific-technical revolution and with a number of social tendencies demand precisely such an approach, as has been acknowledged in a number of official statements.

„Human beings hold two types of theories of action. There is the one that they espouse, which is usually expressed in the form of stated beliefs and values. Then there is the theory that they actually use; this can only be inferred from observing their actions, that is, their actual behavior.“

„While economic theory in general may be defined as the theory of how an economic condition or an economic development is determined within an institutional framework, the deals with how to judge whether one condition can be said to be better in some way than another and whether it is possible, by altering the institutional framework, to achieve a better condition than the present one.“
