Kant’s philosophy of mind is situated in-between that of Newton and Leibniz. Newton believed that space and time are absolute and objective, separate from our mind and wholly deterministic. This determinist outlook did not appeal to Kant, since with this view Kant believed he could not argue in favour of freedom, morality, or God. At the opposite end is Leibniz, who believed that everything has a soul with a ‘set of God-given perceptions’. The universe is essentially many enclosed and isolated souls. Kant sat between these two viewpoints, and argued that time and space are wholes composed of parts, and that time and space are faculties inside our minds, like containers, and are empty, needing to be filled with sensory experience. To have any experience, time and space must exist.
As seen before in part 1, Kant was heavily influenced by Aristotle, and took from him the concept of the nature of humans as well as Aristotelian logic. Kant, like Aristotle, held that humans are by nature rational. The faculties of sensibility (responsible for ‘intuitions’) and understanding (responsible for ‘concepts’) work together to create reality. Kant relies on truth being stable, and creates categories, or pure concepts, which correspond to forms of logical judgement.
