"For Schumpeter, capitalism itself could not possibly make for conquest and war: its spirit was rational, calculating, and therefore averse to risk-taking on the scale implicit in warmaking and in other heroic antics. Interesting as they were as a counterpoint to the various Marxist theories of imperialism, Schumpeter's views evinced less awareness of the knottiness of the problem he was dealing with than those of Adam Ferguson and Tocqueville that have just been recalled. To go back even further: Cardinal de Retz, with his insistence that the passions are not to be counted out in situations where interest-motivated behavior is considered to be the rule, appears to have had the better part of the argument than either Keynes or Schumpeter."
