Vaisheshika (sh)

One of the six orthodox systems, or darshans, of Indian philosophy.

Founded §ã 2nd-3rd century AD, it fused with Nyaya in the 11th century, forming the Nyaya-Vaisheshika school. Vaisheshika attempts to identify, inventory, and classify the entities that present themselves to human perception. It lists seven categories of being. It holds that the universe's smallest, indivisible, indestructible unit is the atom, which is made active through God's will, and that all physical things are a combination of the atoms of earth, water, fire, and air.
