Lev Lopatin

In his two-volume magnum opus Polozhitel'nye zadachi filosofii (The Positive Tasks of Philosophy), L. Lopatin (1855-1920), who taught at Moscow University, defended the possibility of metaphysical knowledge. He claimed that empirical knowledge is limited to appearances, whereas metaphysics yields knowledge of the true nature of things. Although Lopatin saw Hegel and Spinoza as the definitive expositors of rationalistic idealism, he rejected both for their very transformation of concrete relations into rational or logical ones. Nevertheless, Lopatin affirmed the role of reason particularly in philosophy in conscious opposition to, as he saw it, Solovyov's ultimate surrender to religion. In the first volume, he attacked materialism as itself a metaphysical doctrine that elevates matter to the status of an absolute that cannot explain the particular properties of individual things or the relation between things and consciousness. In his second volume, Lopatin distinguishes mechanical causality from "creative causality," according to which one phenomenon follows another, though with something new added to it. Despite his wealth of metaphysical speculation, quite foreign to most contemporary readers, Lopatin's observations on the self or ego derived from speculation that is not without some interest. Denying that the self has a purely empirical nature, Lopatin emphasized that the undeniable reality of time demonstrated the non-temporality of the self, for temporality could only be understood by that which is outside time. Since the self is extra-temporal, it cannot be destroyed, for that is an event in time. Likewise, in opposition to Solovyov, Lopatin held that the substantiality of the self is immediately evident in consciousness.
