Theory of Everything (philosophy) - Comprehensive Philosophical Systems

Comprehensive Philosophical Systems

The "system building" style of metaphysics attempts to answer all the important questions in a coherent way, providing a complete picture of the world. Plato and Aristotle could be said to be early examples of comprehensive systems. In the early modern period (17th and 18th centuries), the system-building scope of philosophy is often linked to the rationalist method of philosophy, that is the technique of deducing the nature of the world by pure apriori reason. Examples from the early modern period include the Leibniz's Monadology, Descarte's Dualism, Spinoza's Monism. Hegel's Absolute idealism and Whitehead's Process philosophy were later systems.

Other philosophers do not believe its techniques can aim so high. Some scientists think a more mathematical approach than philosophy is needed for a TOE, for instance Stephen Hawking wrote in A Brief History of Time that even if we had a TOE, it wouldn't necessarily be a set of equations. He wrote, “What is it that breathes fire into the equations and makes a universe for them to describe?”.
