During its inception, the greatest subject of interest for early philosophers was: the physical realm and its components, the question of ‘What are things made of?’. In its most basic form, this laid the groundwork for the first branch of philosophy called metaphysics. In a sense, metaphysics is the fountainhead of modern science. It was the theories proposed by ancient Greek philosophers and their findings of atoms and elements – chemistry, the physical space and matter – physics, and the living creatures – biology, is that gave rise to evidence-based research that we call science.
Nonetheless, like any other branch of philosophy, metaphysics expanded far beyond typical inquiries about the physical realm into searching for the true nature of being, existence, and what can not be seen; more complex notions such as defining the cosmos. For a long time, a number of philosophers have questioned the validity of metaphysics, calling it a study based more on intuition than on evidence. However, current scientific advancements in areas such as quantum mechanics and the discovery of the black hole had sparked significant interest in metaphysics and prior theories.
