What does Hylas mean by “to exist is one thing and to be
perceived is another”?
1. Why does Philonous reject the notion of a material

2. What conclusion does Philonous eventually force Hylas
to accept regarding perceptions?
3. Why does the world continue to exist when we are not perceiving
it, for example, when we are asleep?
