In this essay I defend the claim that the life of a living being is not one of its properties but something different: a mode of being. It follows from this that living beings should not be taken to be things that possess the property of being alive. Second, I argue that living beings are essentially involved in ongoing activities as long as they exist. Life cannot only be a disposition to be active, but must itself be an ongoing activity. Third, I suggest that for something to be a living being is to engage in activities whose success is determined by criteria that emerge exclusively from a proper account of the nature of the living being in question. To identify something as a living being is not to attribute a particular property to it, but to say what criteria apply to what it actually is or does.

Obwohl ‚conscientia’ ein zentraler Grundbegriff der cartesischen Metaphysik ist, sagt Descartes nirgends explizit, was er damit meint. Auch aus der Art und Weise, in der er das Wort verwendet, lässt sich dessen Bedeutung nicht vollends erschließen. Insbesondere handelt es sich nicht um einen reflexiven Denkakt (cogitatio), nicht um eine Disposition zum Haben solcher cogitationes und nicht um eine Art Aufmerksamkeit. Um die Bedeutung des Begriffes zu klären, schlage ich vor, auf klassische Texte von Augustinus, Thomas von Aquin und jesuitischen Autoren zurückzugreifen. Es ergibt sich, dass man unter der conscientia traditionell ein Wissen um den moralischen Wert einer Handlung verstand, das der Handelnde mit einem idealen Beobachter (d.i. Gott) teilt. Ich behaupte, dass sich diese Begriffsbestimmung mehr oder weniger analog auf Descartes übertragen lässt. Die cartesische conscientia ist demnach ein Wissen um den spezifischen Wert eines Gedanken, das der Denker mit einem idealen Beobachter teilt.

Descartes claims that God is a substance, and that mind and body are two different and separable substances. This paper provides some background that renders these claims intelligible. For Descartes, that something is real means it can exist in separation, and something is a substance if it does not depend on other substances for its existence. Further, separable objects are correlates of distinct ideas, for an idea is distinct (in an objective sense) if its object may be easily and clearly separated from everything that is not its object. It follows that if our idea of God is our most distinct idea, as Descartes claims, then God must be a substance in the Cartesian sense of the term. Also, if we can have an idea of a thinking subject which does not in any sense refer to bodily things, and if bodily things are substances, then mind and body must be two different substances
