 Second, a demonstration for Hobbes did not involve the derivation of features by means of deduction. Such deductions would provide one with knowledge of what was already contained in the starting proposition, making it difficult to see how commands could be derived from the definition of ‘law of nature’ in Leviathan XIV. However, Hobbes explicitly said that demonstrations should be synthetic, wherein one builds the complex thing to be demonstrated out of simpler constituent parts. A demonstration, Hobbes asserted, should be understood as a showing of some construction to someone else (OL I.76) and, as a result, he claimed that “entire method of demonstrating is synthetic” (OL I.71). By ‘synthesis’ Hobbes means that one shows how something is put together to reach the desired end, one shows how that thing is made.
