Subjectivism Subjectivism argues that because knowledge is confined to ideas in the mind of the knower, it is impossible to get beyond these ideas to an objective or material reality separate from and independent of the knower. Hence, the world is in the knower or belongs to the knower. Even if ideas represented an independent reality, as realism contends, one could not possibly know it. Even if physical objects do not exist when no one is observing them, we can have no reason to suppose that they do for no one can observe them existing unobserved. Objectivism Objectivism believes that objects are independent of mind and present their properties directly to the knower through sense data.
Ideas represent objects.
Josh McDowel serves as a good example of the evidentialist. Corneilus Van Til serves as a good example of the presuppositionalist. Van Til, and other presuppositionalists would not necessarily criticise the work that Josh McDowel does. In fact, they would likely arge that it is useful and necessary. However, it does not quite go far enough in that it fails to deal with the epistemological issues.
