I want to know the answer to the following question:
When was 'Treatise Concerning the Principles of Human Knowledge' published?
All the background I'm provided with is that "In response to Locke, he put forth in his Treatise Concerning the Principles of Human Knowledge (1710) an important challenge to empiricism in which things only exist either as a result of their being perceived, or by virtue of the fact that they are an entity doing the perceiving.". Is that enough to answer the question?
