inct perception of the things to be certain. He concludes that there are three levels of reality, God, Substance, and Properties. Properties are shapes, thought, etc. Substances are greater reality than properties as Bodies and Minds. And God is the greater reality of infinite substance. Also, there are two types of reality, formal and objective. The formal reality is a reality of a thing itself and objective reality is the reality of that which a representation represents. Math is the foundation of the new sciences so he makes the link that Size, shape, and motions are mathematical conceptions. The body can be extended and has modes of size, shape and motion. Mind is a thought system that has the modes of ideas, senses, etc., and mind gives life to the body. Descartes gives his metaphysics based solely on certain foundations and one being math. Math is the only certain thing. As he says many times two plus two will always equal four. Math is the basis for the new science and Descartes builds a certain argument that the body (size, shape, and motion all components of math) and all its extensions are mathematical. The new science is basically Descartes science because he is the originator of his new metaphysics.Locke on the other hand, didnt want to create a new metaphysics. What he wanted to do was to clean up the formalities of the scholastics. There are no innate ideas that Descartes says that everyone has. Locke thinks that the only way to gain knowledge is by sense perception and we are limited to it. Thus, our knowledge of things are also limited. Knowledge of things begins in the senses or by reflection and provides the mind with material of knowledge. Locke calls these materials ideas. Ideas are things that represent the objects. There are two qualities, primary and secondary. Primary qualities are objects (size, shape, weight) from ideas that represent perceived qualities that do not exist in objects except...
