Abstract
Ushenko's speculative vision opened on the problem of time and its relation to logic. Profoundly concerned about the theme of time--the theme that intrinsically defines romantic irrationalism--he yet endeavored to vindicate within the bounds of temporality the sovereignty of logic so essential to the continuance of classical philosophy. The dual preoccupation with time and logic urged him into the fields of symbolic logic and relativity physics. From the flux of unrepeatable events he disengaged the laws of logic and the propositions of scientific discourse, while at the same time he sought to keep both orders of entity united without injury to either. He ventured into nature as disclosed by contemporary physics and selected the category of event to supplant substance. He undertook to expound a metaphysics of events, grappled with the problem of the unity not only of nature but of the singular events that make up nature, and fixed upon the overarching structure of the space-time of relativity physics to resolve the problem. But this did not suffice. The metaphysical vision at work in these early books glimpsed at moments a principle beyond time, beyond propositions, beyond events--the principle of power. Power and Events: An Essay on Dynamics in Philosophy focused on the principle of power, integrating the other themes in terms of it. As the mature work of a significant and original thinker, Power and Events posed the principle of power as the central idea for the future course of philosophical investigation. In pursuit of its implications Ushenko embarked upon the philosophy of art in his last book Dynamics of Art and in a consistent yet startling fashion advanced the thesis that the substance of art is in effect a dynamic equilibrium of powers.
