Hans-Hermann HoppeKant had hinted at this solution. He thought ma<strong>the</strong>matics,for instance, had to be grounded in our knowledge of<strong>the</strong> meaning of repetition, of repetitive operations. And healso realized, if only somewhat vaguel~ that <strong>the</strong> principle ofcausality is implied in our underst<strong>and</strong>ing of what it is <strong>and</strong>means to act. 16Yet it is Mises who brings this insight to <strong>the</strong> foreground:Causality; he realizes, is a category of action. To act meansto interfere at some earlier point in time in order to producesome later result, <strong>and</strong> thus every actor must presuppose <strong>the</strong>existence ofconstantly operating causes. Causality is a prerequisiteof acting, as Mises puts it.But Mises is not, as is Kant, interested in epistemologyas such. With his recognition ofaction as <strong>the</strong> bridge between<strong>the</strong> mind <strong>and</strong> <strong>the</strong> outside reality; he has found a solution to<strong>the</strong> Kantian problem of how true syn<strong>the</strong>tic a priori propositionscan be possible. And he has offered some extremelyvaluable insights regarding <strong>the</strong> ultimate foundation ofo<strong>the</strong>rcentral epistemological propositions besides <strong>the</strong> principle ofcausality; such as <strong>the</strong> law ofcontradiction as <strong>the</strong> cornerstone oflogic. And he has <strong>the</strong>rebyopened a path for future philosophicalresearch that, to my knowledge, has hardly been traveled.Yet Mises's subject matter is economics, <strong>and</strong> so I willhave to lay to rest <strong>the</strong> problem ofexplaining in more detail <strong>the</strong>causality principle as an a priori true proposition.I 716For Kantian interpretations ofma<strong>the</strong>matics see H. Dingler, Philosophic der LogikundMa<strong>the</strong>matik (Munich: 1931); Paul Lorenzen, Einfiihrung in die operative Logikund Ma<strong>the</strong>matik (Frankfurt/M.: 1970); Ludwig Wittgenstein, Remarks on <strong>the</strong>Foundations ofMa<strong>the</strong>matics (Cambridge, Mass.: M.Ll: Press, 1978); also Kambartel,Erfahrung und Struktur, pp. 118-22; for an unusually careful <strong>and</strong> cautiousinterpretation of Kantianism from <strong>the</strong> point ofview ofmodern physics, seeP. Mittelstaedt, Philosophische Probleme der modernen Physik (Mannheim: 1967).17For some far<strong>the</strong>r reaching considerations on <strong>the</strong>se matters, see Hoppe "InDefense ofExtreme Rationalism."The Ludwig von Mises Institute • 21
