Dutch friends had reported to him the views which Spinoza was circulating in manuscript. Cudworth remarks in his Preface that he would have ignored hylozoism had he not been aware that a new version of it would shortly be published. Spinoza's idealism also tends toward hylozoism. In order to hold a balance even between matter and mind, Spinoza combined materialistic with pantheistic hylozoism, by demoting both to mere attributes of the one infinite substance. Although specifically rejecting identity in inorganic matter, he, like the Cambridge Platonists, sees a life force within, as well as beyond, all matter. Contemporary hylozoism Immanuel Kant presented arguments against hylozoism in the third chapter of his Metaphysische Anfangsgründe der Naturwissenschaften ("First Metaphysical Principles of Natural Science," 1786) and also in his famous Kritik der reinen Vernunft ("Critique of Pure Reason," 1783). Yet, in our times, scientific hylozoism – whether modified, or keeping the trend to make all beings conform to some uniform pattern, to which the concept was adhered in modernity by Herbert Spencer, Hermann Lotze, and Ernst Haeckel – was often called upon as a protest against a mechanistic worldview. In the 19th century, Haeckel developed a materialist form of hylozoism, specially against Rudolf Virchow's and Hermann von Helmholtz's mechanical views of humans and nature. In his Die Welträtsel of 1899 (The Riddle of the Universe 1901), Haeckel upheld a unity of organic and inorganic nature and derived all actions of both types of matter from natural causes and laws. Thus, his form of hylozoism reverses the usual course by maintaining that living and nonliving things are essentially the same, and by erasing the distinction between the two and stipulating that they behave by a single set of laws. In contrast, the Argentine-German neurobiological tradition terms hylozoic hiatus all of the parts of nature which can only behave lawfully or nomically and, upon such a feature, are described as lying outside of minds and amid them – i.e. extramentally. Thereby the hylozoic hiatus becomes contraposed to minds deemed able of behaving semoviently, i.e. able of inaugurating new causal series (semovience). Hylozoism in this contemporary neurobiological tradition is thus restricted to the portions of nature behaving nomically inside the minds, namely the minds' sensory reactions (Christfried Jakob's "sensory intonations") whereby minds react to the stimuli coming from the hylozoic hiatus or extramental realm. Martin Buber too takes an approach that is quasi-hylozoic. By maintaining that
