George Berkeley was born in 1685 in Ireland. He was an Anglo-Irish philosopher best known for advancing immaterialism, the theory that objects only exist insofar as they are perceived. According to Berkeley, there are only two kinds of things: spirits and ideas. Spirits are active beings that produce and perceive ideas, while ideas are passive beings that are produced and perceived. Berkeley argued that God is responsible for the existence of ideas since humans do not have direct control over what they perceive through their senses. He made important contributions to philosophy through works such as A Treatise Concerning the Principles of Human Knowledge. Berkeley died in 1753 in Oxford, United States from congestive heart failure.

According to Berkeley there are only
two kinds of things: spirits and ideas.
Spirits are simple, active beings which
produce and perceive ideas; ideas are
passive beings which are produced and
perceived.

7. Berkeley's proof of the existence of God
Whatever power I may have over my own thoughts, I
find the ideas actually perceived by Sense have not a
like dependence on my will. When in broad daylight I
open my eyes, it is not in my power to choose whether
I shall see or no, or to determine what particular
objects shall present themselves to my view; and so
likewise as to the hearing and other senses; the ideas
imprinted on them are not creatures of my will. There
is therefore some other Will or Spirit that produces
them.
