Finally, and of central importance, the special life of the saint—fully separate from the "natural" life of wants and desires—could no longer play it… - Max Weber

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?

After Nietzsche’s devastating criticism of those “last men” who “invented happiness,” there is probably no need for me to remind you of the naïve optimism with which we once celebrated science, or the technology for the mastery of life based on it, as the path to happiness. Who believes this, apart from a few overgrown children occupying university chairs or editorial offices?

Above all, as will be repeatedly apparent in the sections below, fundamental for our discussion is the investigation of the idea of a testifying to one's belief as the psychological point of origin for methodical ethics.
