LOCKE: PRIMARY AND SECONDARY QUALITIES 4 John Locke published his ESSAY Concerning Human Understanding in 1690, and it became a turning point in Western thought Locke made a distinction between primary and secondary qualities. Primary qualities, he held, are to be considered as belonging to physical objects themselves, they inhere in the real object. Primary qualities are such thing as solid ity, extension ( that is, volume, the occupation of space), shape, motion/rest, and number.(Today, still thinking in Locke's terms, we might wish to add such qualities as mass, atomic structure, radioactivity, magnetism, etc. )If we couldn't perceive objects-or if we perceivers didn't exist--these qualities would still exist in objects Secondary qualities are experiences only, stimulated in us by the powers residing in real objects, and these qual ities are: colors, sounds, tastes, odors, odors, weight warmth, etc. Secondary qualities are our subjective human responses to the objective primary qualities. Clearly, we could not have our perceptions unless they are caused by real objects But those primary qualities--what do they really belong to? What is, this"object that has shape or is in motion or is solid? Locke had to answer"substance " But what is"substance"? Well, "substance"is what has shape is in motion, and is so lid That didn 't get us very far, so let's put the question d ifferently: how can we know substance"? The only way we can know substance, Locke answered, is to observe the primary qualities: shape, motion, solid ity, etc. But that's where we were before Locke therefore concludes that"substance"cannot be known directly at all, but is rather an assumption which we are forced to make. After all, how can "shape"exist without a"substance"which is"shaped"? Locke had to admit, therefore, that"substance"is merely a concept on which we hang"the primary and secondary qualities, which we can indeed experience. " So that if any one will examine himself concerning his notion of substances in general, he will find he has no other idea of it at all, but only a supposition of he knows not what support of such qualities This was not a satisfying conclusion, but Locke felt it was both good logic and common sense. After all, who in his right mind could possibly conclude that solid ity and motion and shape might exist but that"substance"might not? The answer to that question is: George Berkeley. BERKELEY THE LOGOC OF IMMATERIALISM 5 By the time he was twenty-five years old, George Berkeley had published is Principles of Human Knowledge, had stirred up international controversy in philosophical and theological circles(he was an Anglican clergy man, later a bishop) and was regarded as one of the most logical, eloquent, and charming philosophers the English-speaking world had produced As early as the age of twenty, Berkeley developed the habit of jotting down ideas arguments, and reflections in notebooks. These autobiographical notes were unknown until they were discovered and published in 1871 and given the title of Commonplace Book. In 1706, when Berkeley was twenty-one, he wrote a paragraph in his notebook

BERKELEY: THE LOGOC OF IMMATERIALISM 5 By the time he was twenty-five years old, George Berkeley had pub1ished his Principles of Human Knowledge, had stirred up international controversy in philosophical and theological circles (he was an Anglican clergyman, later a bishop), and was regarded as one of the most logical, eloquent, and charming philosophers the English-speaking world had produced. As early as the age of twenty, Berkeley developed the habit of jotting down ideas, arguments, and reflections in notebooks. These autobiographical notes were unknown until they were discovered and published in 1871 and given the title of Commonplace Book. In 1706, when Berkeley was twenty-one, he wrote a paragraph in his notebook
which pointed the direction his philosophy would take He wrote that the concept of materialism or"substance"had always been "the main pillar and support of skepticism"on which have been founded all the impious schemes of atheism and irrelig ion... How great a friend material ubstance hath been to atheists in all ages were needless to relate. When this cornerstone is once removed the whole fabric cannot choose but fall to the ground Berkeley began with Locke 's conclusions and went on to prove that substance really doesn t exist 6 How did the lrish philosopher manage it? He did by agreeing with Locke that the idea of substance(or matter)is merely assumption on our part; we can never perceive substance directly. What we experience and the only things we experience are colors, tastes, odors, etc, that is, the secondary qualities But what about the primary qual ities--shape, solid ity, motion/rest, etc.--how do we know about these? We only infer those too, said Berkeley. How do you know the shape of a seashell? You run your fingers over the surface and feel it. Not exactly, Berkeley reminds us; we don't feel it. We only feel our sensations and proceed to assume that matter exists in " seashell" form and that the matter is the cause of our sensations. We further assume that the matter possesses certain (primary )qual ities which we cannot experience d irectly So far, Berkeley seems to agree with Locke. But where Locke never doubts the existence of matter(he merely says we can never know it ), Berkeley asks: If substance is merely an assumption, then could that assumption be wrong? Suppose the world of material objects doesn 't really exist. How could we account for the supposed objects which cause our perceptions? Berkeley concluded that there alternative assumption, just as logical as"substance, and far preferable Assume that God exists, and that he places in our minds all the perceptions which we experience. If we are making assumptions about reality to account for our perceptions, why is the assumption of the matter a more reasonable assumption than the existence of God? And if one is a Christian philosopher, doesn' t the assumption of a God-source become a more likely assumption than a matter-source? This is Berkeley's"immaterial ism--matter does not exist It is merely a fiction we thought we needed. The universe is composed of interacting minds only, and Go is the source of all our perceptions. All the world is merely an interplay of mental images and images and ideas, grandly provided and coord inated by god Therefore, reasoned Berkeley, "to be is to be perceived"--esse est percipi. There are no"real"clouds, rocks, oceans, stars, penguins, or seashells. Such items are but mind-inlages derived from God. Nothing exists, therefore, except when it is being perceived How can we be sure the persistent objects of experience---our homes, friends, the familiar belongings--will"be there"when we want to perceive them? Does the seashell-image flicker off and on, in and out of existence every time we look at it or turn away from it. No, says Berkeley. God is the eternal perceiver, and all images

He wrote that the concept of materialism or "substance" had always been "the main pillar and support of skepticism" on which have been founded “all the impious schemes of atheism and irreligion ......How great a friend material substance hath been to atheists in all ages were needless to relate....When this cornerstone is once removed .the whole fabric cannot choose but fall to the ground ..." Berkeley began with Locke 's conclusions and went on to prove that substance really doesn't exist! 6 How did the Irish philosopher manage it? He did by agreeing with Locke that the idea of substance (or matter) is merely an assumption on our part; we can never perceive substance directly. What we experience _and the only things we experience _are colors ,tastes ,odors ,etc., that is ,the secondary qualities But what about the primary qua1ities--shape, solidity, motion/rest, etc.--how do we know about these? We only infer those too, said Berkeley. How do you know the shape of a seashell? You run your fingers over the surface and feel it. Not exactly, Berkeley reminds us; we don't feel it. We only feel our sensations and proceed to assume that matter exists in "seashell" form and that the matter is the cause of our sensations. We further assume that the matter possesses certain (primary ) qua1ities which we cannot experience directly. So far, Berkeley seems to agree with Locke. But where Locke never doubts the existence of matter (he merely says we can never know it), Berkeley asks: If substance is merely an assumption, then could that assumption be wrong? Suppose the world of material objects doesn't really exist. How could we account for the supposed objects which cause our perceptions? Berkeley concluded that there is an alternative assumption, just as logical as "substance," and far preferable. Assume that God exists, and that he places in our minds all the perceptions which we experience. lf we are making assumptions about reality to account for our perceptions, why is the assumption of the matter a more reasonable assumption than the existence of God? And if one is a Christian phi1osopher, doesn't the assumption of a God-source become a more 1ike1y assumption than a matter-source? This is Berkeley's "immaterialism"--matter does not exist .It is merely a fiction we thought we needed. The universe is composed of interacting minds only, and God is the source of all our perceptions. All the world is merely an interplay of mental images and images and ideas , grandly provided and coordinated by God. Therefore, reasoned Berkeley, "to be is to be perceived "--esse est percipi.

Does the seashel1-image flicker off and on, in and out of existence every time we look at it or turn away from it. No, says Berkeley. God is the eternal perceiver, and a1l images
continue to exist in the mind of God. They are always avail able to us for the asking to be experienced as we would. Indeed, comments Will Durant, "no one since Plato had written nonsense so charmingly. 7 Everyone discussed Berkeley's log ical attempt to annihilate matter among others, the lexicographer Samuel Johnson rejected the system, as Boswell reports After we came out of church, we stood talking for some time together of Bishop Berkeley's ingenious sophistry to prove the non-existence of matter, and that everything in the universe is merely ideal. I observed that though we are satisfied his doctrine is not true, it is impossible to refute it. I shall never forget the alacrity with which Johnson answered striking his foot with a mighty force against a large stone till he rebounded from it "I refute it thus But what had Johnson really proved by kicking the rock? He had merely illustrated and confirmed Berkeley's argument. For al JOhnson"knew"was the sharp pain in his toe, perhaps a numb feeling in his foot, and the sensation of a sudden stop which gave his leg a jar. All he had proven by kicking the rock was that he was capable of feel ing a variety of subjective sensations. All he knew was his own experience, and that, after all, was the point Berkeley was making. So Samuel Johnson had merely added his considerable support to the " philosophy of immaterialism. 8 What else is this. however but " charming non sense " Most of us are convinced(we think) that physical matter exists. It seems to us that Berkeley made a simple mistake, a non sequitur: just because we cannot experience physical matter directly, it does not necessarily follow that matter doesn ' t exist But did berkeley really go wrong? (1) Berkeley emphasizes the fact that we are limited absolutely to our own perceptions and cannot experience any"real"world On this point he seems to be correct. (2)He is therefore repeating Locke's point that nhy ption which we think to be logical necessity. On this point also, he is correct Whether you will go further with Berkeley and accept that his alternat ive assumption--God as the source of experience--is a better one will depend somewhat on personal preference and theological belief. Most of us remain convinced that the reality of matter is a better assumption, but perhaps that's only because we have lived uncritical lly with it most of our lives. We must face honestly, however, berkeley singular challenge: Prove, if you can, that any material object exists apart from your perception of it. If you can, then Berkeley is wrong.
