The striving by which each thing strives to persevere is nothing but the actual essence of the thing (E3p7). This is not a psychological doctrine attributing desire or appetite to rocks and tables; it is a metaphysical doctrine about what it is for a thing to be the thing it is. The argument runs from E3p4 through E3p7. No thing can be destroyed except through an external cause (E3p4): the definition of a thing affirms the thing's essence and cannot, taken alone, destroy that essence; destruction must come from outside the essence. Things are of contrary nature insofar as one can destroy the other (E3p5): contrariety is the relation that makes external destruction possible. Therefore each thing, insofar as it is in itself — that is, considered with respect only to its own essence and not to external causes — strives to persevere in its being (E3p6). The striving is the actual essence; what it is for a thing to be is for it to maintain itself in existence against the external causes that would destroy it. The apparent counterexamples — the burning candle that consumes itself, the suicidal person, the dying sun — are addressed by the qualification quantum in se est (insofar as it is in itself): the destruction in each case follows from external causes that have so altered the thing that it is no longer in the state in which its essence operates. In each case the destruction is the work of external causes overwhelming what the essence, taken alone, would maintain.","paragraphs":[[{"t":"Each thing, insofar as it is in itself, strives to persevere in its being (E3p6).","n":[]},{"t":"The striving by which each thing strives to persevere is nothing but the actual essence of the thing (E3p7).","n":[]},{"t":"This is not a psychological doctrine attributing desire or appetite to rocks and tables; it is a metaphysical doctrine about what it is for a thing to be the thing it is.","n":[]}],[{"t":"The argument runs from E3p4 through E3p7.","n":[]},{"t":"No thing can be destroyed except through an external cause (E3p4): the definition of a thing affirms the thing's essence and cannot, taken alone, destroy that essence; destruction must come from outside the essence.","n":[1]},{"t":"Things are of contrary nature insofar as one can destroy the other (E3p5): contrariety is the relation that makes external destruction possible.","n":[]}],[{"t":"Therefore each thing, insofar as it is in itself — that is, considered with respect only to its own essence and not to external causes — strives to persevere in its being (E3p6).","n":[]},{"t":"The striving is the actual essence; what it is for a thing to be is for it to maintain itself in existence against the external causes that would destroy it.","n":[]},{"t":"The apparent counterexamples — the burning candle that consumes itself, the suicidal person, the dying sun — are addressed by the qualification quantum in se est (insofar as it is in itself): the destruction in each case follows from external causes that have so altered the thing that it is no longer in the state in which its essence operates.","n":[]},{"t":"In each case the destruction is the work of external causes overwhelming what the essence, taken alone, would maintain.","n":[2,3]}]],"texts":"Ethics E3p4 ('No thing can be destroyed except through an external cause'); E3p5 ('Things are of a contrary nature, that is, cannot be in the same subject, insofar as one can destroy the other'); E3p6 ('Each thing, insofar as it is in itself, strives to persevere in its being'); E3p7 ('The striving by which each thing strives to persevere in its being is nothing but the actual essence of the thing'); E3p8-p11 (the application to mind and body together); E4p20s (the discussion of suicide as overcoming of conatus by external causes); the Cartesian background in Descartes's Principles of Philosophy 2.37 and 3.56.

The Cartesian inheritance is direct (Descartes's Principles 2.37 on the law of inertia and 3.56 on conatus to motion); Hobbes had developed a related notion in Leviathan I.6. Leibniz's monadic conatus generalized the doctrine in a different direction. Della Rocca's Cambridge Companion chapter (2022) reconstructs the argument from E3p4-p7 with care and identifies the rationalist commitments that ground each step. The contemporary scientific engagement runs through Antonio Damasio's Looking for Spinoza (2003), which reads the conatus as the metaphysical anticipation of homeostatic self-regulation in living systems. The standard counterexamples — suicide, self- destructive behavior, the burning candle — are addressed in E4p20s by appeal to the qualification quantum in se est; whether the qualification carries the weight it must carry remains the contested point in the secondary literature.","era":"1632-1677","discipline":"Philosophy","refs":[{"n":1,"work":"Ethics","page":"","canonical":"","quote":"PROP.
