Answer
Hylas, representing John Locke's philosophical viewpoint, embodies the counterarguments to George Berkeley's ideas. Hylas challenges Berkeley's theory of immaterialism, asserting that physical objects exist independently of the mind and have real, inherent qualities. Through their philosophical discussions in Berkeley's dialogues, particularly the "Three Dialogues between Hylas and Philonous," Hylas presents objections and raises philosophical questions that bring to light the limitations and complexities of immaterialism.
