Two Types of Skepticism It is common for philosophers to use the phrase “skepticism with regard to the external world” or “skepticism about other minds”.

The two conclusions are in obvious tension with each other, […]
Referring, Knowing, and Skepticism What would it take to defeat the skeptic? What conception of knowledge is best suited to fending off the skeptical challenge?

Thus God, space, time, and number: anyone who grasps these concepts is apt to entertain thoughts of the infinite. God is infinitely powerful, space is unending, time goes on forever, and numbers […]
