Berkeley's Treatise Concerning the Principles of Human Knowledge was published three years before the publication of Arthur Collier's Clavis Universalis, which made assertions similar to those of Berkeley's.
Berkeleyn teos Treatise Concerning the Principles of Human Knowledge julkaistiin kolme vuotta ennen Arthur Collierin teosta Clavis Universalis, joka esitti samanlaisia ajatuksia kuin Berkeley teoksessaan.
