This essay proposes a comprehensive blueprint for the hylomorphic foundations of cosmology. The key philosophical explananda in cosmology are those dealing with global processes and structures, the regularity of global regularities, and the existence of the global as such. The possibility of elucidating these using alternatives to hylomorphism is outlined and difficulties with these alternatives are raised. Hylomorphism, by contrast, provides a sound philosophical ground for cosmology insofar as it leads to notions of cosmic essence, the unity of complex essences, (...) and globally emergent properties. These are used as the basis to account for the aforementioned cosmological explananda and to resolve two problems in the philosophy of cosmology: the meta-law dilemma and the uniqueness of the universe. In summary, cosmology needs hylomorphism because it is able to ground cosmology’s efforts as a scientific inquiry. It can do so because hylomorphism philosophically accounts for changing substances and aggregates of substances, the various scales of law-governed behavior measured by the natures of those substances, and how those substances as parts relate to the universe as a whole.

The problem of unifying knowledge represents the frontier between science and philosophy. Science approaches the problem analytically bottom-up whereas, prior to the end of the nineteenth century, philosophy approached the problem synthetically top-down. In the late nineteenth century, the approach of speculative metaphysics was rejected outright by science. Unfortunately, in the rush for science to break with speculative metaphysics, synthetic or top-down philosophy as a whole was rejected. This meant not only the rejection of speculative metaphysics, but also the implicit (...) rejection of empirically-led synthetic philosophy and the philosophy of nature. Since a change in the paradigm of science requires a change in the philosophy of nature underpinning science, the rejection of the philosophy of nature closes science to the possibility of a paradigm change. Given the foundational problems faced by science, there is a need for empirically-led synthetic philosophy in order to discover a new empirically-based philosophy of nature. Such a philosophy of nature may open science to the possibility of a paradigm change. (shrink)
