He defined science as the demonstrated knowledge of the causes of things, of which there are four types: the material cause,"that from which, as its constitutive material, something comes, for example the bronze of the statue"; the formal, or ideal, cause, what the particular stature is ,its essence of nature, such as its being a bust of plato; the efficient cause, that by which it initially comes into existence,"the source of the first beginning of change," as in "the father is the cause of the child"; and the final cause, its "end" or purpose,"that for the sake of which" something is done, such as "health is of walking around."

亚里斯多德通过严格的演示，探究事物的缘由，用以界定科学。他探究事物的模型有如下四类：物质原因，&由何物所构成，成分，如铸像之青铜&；第二类是形式、想象，如是非常之境况，事物之本质，诸如&柏拉图之名相&；第三类是动因，任何存在凭此而来，&变化伊始的本源力量&，正如&父为子之因&；最后一类是终极之因，作为&事已定&的结论而存在，&健康是走路走出来的&。
