Abstract

Ernst Mach’s economic theory, simply categorized as “principle of economy”, reveals, instead, to a greater extent its complex theoretical nature, that could be summarized in three different concepts: the “economy of thought”, applied to every scientific mind, the “economy of nature”, valid without exception in the whole nature, and the “biological economy”, an original mixture of them, extended to all living organisms. This third concept is clearly meant to limit the most extreme consequences deriving from the other two ones.
