 The most consistent theme of his philosophical writings, are arguments for demonstrating the existence and providential nature of God. The foundation stone of More’s philosophical and apologetic enterprise is his philosophy of spirit, especially his arguments for the existence of incorporeal causal agents, that is, souls or spirits. Furthermore, More attempted to answer materialists like Thomas Hobbes whom he regarded as an atheist. More’s strategy was to show that the same arguments that materialists use demonstrate the existence and properties of body, also support the obverse, the existence of incorporeal substances. In this way More sought to demonstrate that the idea of incorporeal substance, or spirit, was as intelligible as that of corporeal substance, i.e. body. Like Plato (in Laws 10), More argues that the operations of the nature cannot be explained simply in terms of the chance collision of material particles. Rather we must posit some other source of activity, which More identifies as ‘spirit’. It is a short step, he argues, from grasping the concept of spirit, to accepting the idea of an infinite spirit, namely God.
