Michael Williams (born 6 July 1947) is a British philosopher who is currently Krieger-Eisenhower Professor in the Department of Philosophy at Johns Hopkins University, noted especially for his work in epistemology.
With this solution to the skeptical problem, Williams thereby defends a contextualist view of knowledge, but one that differs considerably from other contextualists such as Stewart Cohen and Keith DeRose.
In addition to working on skepticism as a theoretical problem, Williams has a strong interest in the historical development of the skeptical tradition and defends the view that skeptical arguments in modern and contemporary philosophy differ in fundamental ways from similar or related arguments developed in antiquity.
He purposes to explain why the rejection of absolute justification does not raise objections to relativism.
Considering that the set of epistemic beliefs are found in a system in a justified way, even if we suppose that this system of beliefs is coherent, one can have the problem of the circularity of justifications.
