No empire of morality over the forms of the spirit.
Hence is apparent the remarkable fatuity of those who pretend to regulate morally the function of art, of science, or of economy and profess moralistic theories of art and philosophy and a moralized economic science. The poet, the man of science, the business man, must be as honest as others, but it is not given to them to tear in pieces the nature of poetry, of science and of industry, in the madness of honesty. Indeed, were this done or attempted, and the poet were to introduce extraneous elements into his work of art, through his failure to understand morality, or the philosopher to veil or alter the purity of truth, or the man of business foolishly to bring his own business to ruin, then and only then, would they be dishonest. To substitute the single acts of life that appertain to morality, for the universal forms of the spirit, and to predicate of these what should be predicated only of those, is so evident an absurdity that it could not be committed by anyone accustomed to philosophical distinctions. But what nonsense is so evident that idle babblers and elegant men of letters do not know how to cover with their ratiocinative and æsthetic flowers and to present to society or to the academic world as truth, or at least as a theory worthy of reflection and discussion?
Inexistence of other practical forms and impossibility of subdivision of the two established.
Such, then, are the two forms of the practical activity, and such their relation; and as it is not possible to reduce them to one alone, so it is not possible to multiply them beyond the two, which altogether exhaust the nexus of finite and infinite. Hence, too, we perceive that the economic and also the ethic-economic activity do not each of them give rise to new subdivisions, because other terms of subdivision are not conceivable beyond the duality of finite and infinite. As there are no philosophical and ethical classes, nor categories of expression (rhetoric), nor categories of concepts (formalistic logic), so there are no economic categories and ethical categories beyond those that constitute utility (volition of the individual) and morality (volition of the universal).
V
THE PHILOSOPHY OF ECONOMY AND THE SO-CALLED SCIENCE OF ECONOMY
Problem of the relations between Philosophy and Science of Economy.
Internal observation, confirming at all points rational necessity, has rendered clear the existence of a special form of practical activity, the utilitarian or economic, and of a correlative Economic or Philosophy of economy. But however irrefutable may seem the demonstration that we have given, yet it will never be altogether satisfactory, while a very important point is left obscure: the relation between our Philosophy of economy and the Science of economy.
