The theory of gravity explains how objects fall. Philosophical theories are proposed to explain ideas. For example, the theory of mind explains how we think about other people. The theory of justice explains what is fair. Theories can also be proposed to explain events. For example, the theory of the Big Bang explains how the universe began.
