    Aristotle

    Aristotle famously rejected Plato's theory of forms, which states that properties such as beauty are abstract universal entities that exist independent of the objects themselves. Instead, he argued that forms are intrinsic to the objects and cannot exist apart from them, and so must be studied in relation to them.

    John Dalton

    Although two centuries old, Dalton's atomic theory remains valid in modern chemical thought. All matter is made of atoms. Atoms are indivisible and indestructible. Compounds are formed by a combination of two or more different kinds of atoms.
