 This also leads to an attempt to provide separate domains for material and spiritual being. Bacon is adamant on this point: spiritual and material being are entirely separate. Natural causation occurs “naturally,” according to regular processes or laws of nature. There is no “spiritual being” in the material medium as was commonly taught by other scholastic philosophers. That is, Bacon objected to the use of the term ‘spiritual being in the medium’. No, for Bacon, universal causation is corporeal and material, and matter itself is not just pure potentiality but is rather something positive in itself. So, in terms of explaining ‘spiritual/intentional being’ in the medium, Bacon is of the view that the introduction of such terms muddy the waters, especially if you are trying to come up with a comprehensive doctrine of physical force. Hence, the general philosophy of nature prepares the theoretical ground for the specific application of mathematics to matters of vision and perception. It also allows for and requires a metaphorical extension of these terms to moral and religious domains.
