The second-order cybernetics worked out by Heinz von Foerster is rightly held to be a constructivist theory, if no an a manifesto for operational constructivism. The reverse doesn't apply, however. Constructivist epistemologies do not necessarily have the rigor of a cybernetics of cybernetics. One can obeserve congnitions as constructions of an observer, without linking with this the theory that the observing observer observes himself or herself as an observer.

The existence of analogies between central features of various theories implies the existence of a general theory which underlies the particular theories and unifies them with respect to those central features. This fundamental principle of generalization by abstraction was enunicated by the eminent American mathematician E. H. Moore more than thirty years ago. It is the purpose of the pages that follow to work out its implication for theoretical and applied economics.

I do not have the professional knowledge to write a scholarly article about Spinoza. But what I think about this man I can express in a few words. Spinoza was the first to apply with strict consistency the idea of an all-pervasive determinism to human thought, feeling, and action. In my opinion, his point of view has not gained general acceptance by all those striving for clarity and logical rigor only because it requires not only consistency of thought, but also unusual integrity, magnamity, and - modesty.

Game theory concepts were first explicitly applied in evolutionary biology by Lewontin (1961). His approach, however, was to picture a species as playing a game against nature, and to seek strategies which minimised the probability of extinction. A similar line has been taken by Slobodkin & Rapoport (1974). In contrast, here we picture members of a population as playing games against each other, and consider the population dynamics and equilibria which can arise.

Those who proclaim and apply to poetic works a "theory of criticism," a "theoretical hermeneutic" are, today, the masters of the academy and the exemplars in the high gossip of arts and letters. Indeed, they have clarioned "the triumph of the theoretical." They are, in truth, either deceiving themselves or purloining from the immense prestige and confidence of science and technology an instrument ontologically inapplicable to their own material. They would enclose water in a sieve.

As result a new kind of theory to be applied on a class of motions ... these geometric motions are that which acquire different parts of a system of bodies, without neither perturb themselves nor the other and consequently these motions do not depend of the action or reaction among the bodies, but only upon the conditions of their connections, and thus being determined only by geometry and not dependent of the rules of dynamics.
