Bishop George Berkeley was a philosopher from seventeenth century Ireland who is well known for advancing the theory of immaterialism, now called subjective idealism. This theory holds that only minds and the contents within them exist and that all sensation that we experience is directly attributed to God. Berkeley hoped that this theory would lead to a greater dependence and trust in God, as He would be the constant sustainer and provider in a way that traditional Christianity did not attribute Him. There were and are many objection to Berkeley’s doctrine, but one, in particular, stands above the rest for its amusing tone. Dr. Samuel Johnson, a famous English man of letters, heard Berkeley’s theory and, in disgust, kicked a large stone …show more content…

In fact, he did not think that a person could learn in any other manner. However, he and philosophers of similar dispositions, faced a problem, their senses could be mistaken. According to the Stanford Encyclopedia of Philosophy, “The idea is that the sense-data “interpose” themselves between perceivers and the mind-independent objects which we normally take ourselves to be perceiving, and therefore leaves our perceptual, cognitive and epistemic access to the world deeply problematic if not impossible.” As Locke holds that there is a type of correspondence between physical objects and an individual’s ideas, he needed to respond to this problem. He did so by deciding that the characteristics of physical objects must be split into two types of qualities, primary and secondary. These are the differences between true reality and reality that we sense. Essentially, he thought that most real aspects of objects were their primary qualities, such as mass, solidity, height, weight, and mobility. These were aspects that could be mathematically proven and were therefore the truest. Therefore our ideas, or rather our senses, are what allow us to perceive reality on a secondary level. They are aspects like color, taste, texture, sound, and smell and they are subjective. Primary qualities have nothing to do with the perceiver, just the object, but the secondary qualities are …show more content…

Already, having agreed with Locke on his matter, he had lost faith in what his senses informed him about the apple. However, he realized that one cannot perceive some qualities about the apple while disregarding others. One cannot identify an apple’s shape without also identifying it’s color. In fact, one cannot detect any primary qualities without also considering the secondary qualities. You cannot attempt to see an apple without its color, it would simply be imagined as black, white, or opaque. If one attempts to remove the apple’s secondary qualities in an attempt to reach its primary qualities, then you are left with no apple at all. Secondary qualities and primary qualities are inextricably connected, it is impossible to have one without the other. This means that, if secondary qualities were already proven to be untrustworthy, then therefore, primary qualities cannot be trusted either. “The bottom line is that we have no clear understanding of matter. Rather it’s described negatively as inert, senseless (incapable of sensing) substance, which has primary qualities, but qualities are sense perceptions and it is contradictory to suppose that sense perceptions can exist unperceived” (Tlumak, 178). This leads Berkeley to the startling conclusion that matter does not exist; there are only perceptions and disembodied perceivers. As Berkley succinctly puts it, esse est percipi, to be is be
