William of Ockham (1280's-1340's)

Occam's Razor

1300

Although William of Ockham did not create the principle of Occam's razor, he uses the principle in numerous ways. This is how it becomes associated with him. The principle implies that the simpler theory is more likely to be true. Ockham used this principle to limit the number of hypotheses he had. Kaye, Sharon.

Natural Philosophy

1320

To William of Ockham believed in what we know is always in a sense of the metaphysical individual. Also that there is no need for math, because the knowledge is gained from experience. Two things from different species also can not be compared.

Rejection of Species

1321

Ockham's theory of knowledge rejects the theory of species. This theory is not supported by experience, and our cognitive processes revealed no such species. This was perceived as important to the development in the late medieval epistemology.

Mental Language

1323

William of Ockham is credited with being one of the first to provide analytics of the mental language. Mental language differs from written or spoken languages, because it can not be experienced by others.
