George  Berkeley (1685-1753) was the Anglican Dean of Derry (1724), bishop of Cloyne (1734) and an important philosopher belonging to the school of idealism. Born in Ireland, Berkeley moved to Oxford in 1752 and became one of the so-called British empiricists.

Berkeley believed that the material world exists as an idea created in our minds, ultimately by God. In his New theory of Vision (1709), he argued that our sense of distance isn’t directly perceived but inferred from the repeated association of visual and tactile cues. All of existence, itself, is a group of interacting minds, connecting with archetypes, which themselves derive from God.

He uttered the famous line, perhaps adapted from Shakespeare,

To be is to be perceived or a perceiver.

This means that existence is either a mind or stimuli in a mind.

One way that Berkeley tried to support his view was to note that the idea of heat – what the philosopher John Locke called  a “secondary quality” – is somewhat relative. If one of our hands is cold and the other hot, and we place them into warm water, the one hand feels hot and the other cold. Anyone can do this little experiment and see that it’s true. However, Berkeley added that Locke’s so-called “primary qualities” (e.g. shape, quantity) were also dependent on a perceiving mind. Berkeley, in fact, challenged the entire distinction between primary and secondary qualities, as elaborated upon at Wikipedia:

Berkeley maintains that the ideas created by sensations are all that people can know for sure. As a result, what is perceived as real consists only of ideas in the mind. The crux of his argument is that once an object is stripped of all its secondary qualities, it becomes very problematic to assign any acceptable meaning to the idea that there is some object. Not that we can’t picture to ourselves (in our minds) that some object exists apart from any perceiver—we clearly think we can do this—but rather, can we give any content to this idea in any particular case?¹

A slightly different take on the belief that the material world doesn’t exist independent of the mind has been popularized in many books reporting recent discoveries in sub-atomic physics, such as Gary Zukav’s The Dancing Wu Li Masters and Fritzoff Capra’s The Turning Point.
