are psychological laws and theories on a par with those of physics. The absence of a general theory does not imply that those relations are missing or unhpportant in psychology; the discovery and specification of relations is the process by which those theories are built.

Minimization of Convex Functionsr space ., such that a convex function is automatically minimized by . ∈ . at which its Gâteaux variations vanish.. Moreover, in the presence of strict convexity, there can be at most one such .. A large and useful class of functions is shown to be convex.

Variational Principles in Mechanicstions of Euler-Lagrange for the minimizing function made it natural for mathematicians of the eighteenth century to ask for an integral quantity whose minimization would result in Newton’s equations of motion. With such a quantity, a new principle through which the universe acts would be obtained. T
