No one any longer knows who will live in this steel-hard casing and whether entirely new prophets or a mighty rebirth of ancient ideas and ideals wil… - Max Weber

The problem — the experience of the irrationality of the world — has been the driving force of all religious evolution. The Indian doctrine of karma, Persian dualism, the doctrine of original sin, predestination and the deus absconditus, all these have grown out of this experience. Also the early Christians knew full well the world is governed by demons and that he who lets himself in for politics, that is, for power and force as means, contracts with diabolical powers and for his action it is not true that good can follow only from good and evil only from evil, but that often the opposite is true. Anyone who fails to see this is, indeed, a political infant.

This striving becomes understood completely as an end in itself—to such an extent that it appears as fully outside the normal course of affairs and simply irrational, at least when viewed from the perspective of the "happiness" or "utility" of the single individual. Here, people are oriented to acquisition as the purpose of life; acquisition is no longer viewed as a means to the end of satisfying the substantive needs of life. Those people in possession of spontaneous, fun-loving dispositions experience this situation as an absolutely meaningless reversal of a "natural" condition (as we would say today). Yet this reversal constitutes just as surely a guiding principle of [modern] capitalism as incomprehension of this new situation characterizes all who remain untouched by [modern] capitalism's tentacles.

This naive manner of conceptualizing capitalism by reference to a “pursuit of gain” must be relegated to the kindergarten of cultural history methodology and abandoned once and for all. A fully unconstrained compulsion to acquire goods cannot be understood as synonymous with capitalism, and even less as its “spirit.” On the contrary, capitalism can be identical with the taming of this irrational motivation, or at least with its rational tempering. Nonetheless, capitalism is distinguished by the striving for profit, indeed, profit is pursued in a rational, continuous manner in companies and firms, and then pursued again and again, as is profitability. There are no choices. If the entire economy is organized according to the rules of the open market, any company that fails to orient its activities toward the chance of attaining profit is condemned to bankruptcy.
Let us begin by defining terms in a manner more precise than often occurs. For us, a "capitalist" economic act involves first of all an expectation of profit based on the utilization of opportunities for exchange; that is of (formally) peaceful opportunities for acquisition. Formal and actual acquisition through violence follows its own special laws and hence should best be placed, as much as one may recommend doing so, in a different category. Wherever capitalist acquisition is rationally pursued, action is oriented to calculation in terms of capital. What does this mean?
