 As noted, “The end in keeping with which the kind of means to be used is determined is also considered a cause”.This conceptualization of instrumentality as means and ends leads the question further into causality, suggesting that “[w]herever ends are pursued and means are employed, wherever instrumentality reigns, there reigns causality”.To question causality, Heidegger starts from what “[f]or centuries philosophy has taught” regarding the traditional "four causes”.
