George Berkeley was an English philosopher in the empiricist school. In this short treatise, he put forward many of his most influential ideas, including his critique of intellectual abstraction, and the dependence of reality on perception.Unlike many other philosophers I've come across, Berkeley is direct and terse. He does not insult the reader's intelligence by dwelling unnecessarily on one topic, but moves forward at a brisk pace. Further, his writing is clear, organized, and he actively seeks to anticipate any objections that others might have to his points. This combination serves to make the Principles of Human Knowledge an enjoyable read.
I believe that this work can be read advantageously by anybody. However, those reader's who have knowledge of Descartes and Locke might get quite a bit more out of it. Much of what is contained in this little work is an elaboration, refinement, and at times a refutation of Locke's points in An Essay Concerning Human Understanding. In that work, Locke famously argues that the mind is a "blank slate" and that all of our thoughts are ultimately beholden to our experience. The "self" could not exist without sensation. Locke also points out that our sensations are only secondary qualities of objects. The primary qualities, or the arrangement of particles that actually make up an object, are largely unknowable. But Locke still believes they're there.
This was largely a response to Descartes and the rationalist school. In his Discourse on Method and Meditations, Descartes takes a sceptic stance, and maintains that all we perceive cannot be accepted as true. After all, we perceive things in dreams, but nobody thinks that those actually happen. He then concludes that all we can be sure of to exist is ourselves, and God. All external reality is doubtful.
Berkeley's position is the exact reverse. Far from saying that we should not trust our senses, Berkeley argues that nothing exists without us perceiving it. Instead of senses being an imperfect window to reality, or untrustworthy phantasms, sensations become synonymous with reality. (This goes further than Locke, as Berkeley argues that no such "primary qualities" exist, only secondary.) Descartes finds God as he meditates within himself. Berkeley finds God in everything we see, hear, touch, taste, and smell. The two views could not be more dissimilar.
I would suggest this little book to any who wish to learn more about philosophy, but don't want to get bogged down in a 400 page book. It's enjoyable, short, and surprisingly relevant.

Berkeley has often been misrepresented as being a philosopher th Out of Spinoza, Locke, Descartes, Hume and Berkeley, I certainly found Berkeley the most interesting; but, then, I am into Idealism, so it is to some degree understandable and indicates my bias really. Out of 17th-early 18th century philosophers, Berkeley intrigues me as much as Leibniz does. I might, if I were to expand philosophy to include quasi-mystical writers of the same era, include Swedenborg, Hutchinson, Boehme and Sterry.
Berkeley has often been misrepresented as being a philosopher that denied the existence of matter in the sense of real external objects. This is definitely not accurate. Some of his statements are ambiguous and can be wrenched from context and made to look like he supported the non-reality of the outside physical world, but, really, he denied the existence of matter in the philosophical sense of a substrate made up of abstracted accidents and qualities. Like other Idealists going back to Plato, Berkeley believed in a universal Spirit or Mind that necessitates that all reality is perceived and cannot exist apart from this perception. It is an interesting theory when one notes that quantum mechanics supports the notion that reality at the particle level does seem to presuppose an observer. It seems that there may be very current scientific support for Berkeley's supposition on some level.
It does seem that in the concluding remarks that Berkeley supports some kind of pantheism; at least, some of his statements appear to strongly support that reading. Pantheism I do not support, so I have some reservations about Berkeley's philosophy, but it is well worth studying at least. It is also interesting that Berkeley appears to have anticipated the pseudo-spiritual abstract philosophy of German Idealists like Hegel; of course, while anticipating it he was also against any such marriage of spirituality with abstract knowledge systems.
As it stands, Berkeley was a worth while read and I may revisit this work in the future. ...more

I gave it three stars because:
(1) As an argument for idealism, and the first I've ever read, it was fascinating.
(2) Even though his argument for idealism is pretty lousy, the comprehensive philosophy he builds out of it--whereby he makes an, admittedly lousy, argument for God's existence and solves many dilemmas and paradoxes that have puzzled philosophers, scientists, and mathematicians throughout history--is impressively coherent and once again fascinating.
Still, it gets no more than three stars because the argument for idealism is kind of careless, especially because Berkeley says ad nauseam that his position is so obviously right and his argument so compelling that it would be absurd to disagree. I actually found many of his points at the very beginning, for example that "our sensory experiences are only of ideas, not things external to us" compelling, but he drew some pretty careless inferences (e.g. nothing exists outside of our minds) from that pretty uncontroversial first premise. I guess the root of my disagreement with him is that I reject his likeness principle, which is the whole foundation of his attack against the representationalist theory of perception and thus his idealism. I call his argument careless because he provides no argument for this crucial principle and then goes on to insist repeatedly that no one can sanely reject his position. I also found uncompelling his response to one very important materialist claim, the claim that even if we can't know for sure that an external world exists, it is more likely that it does than does not. Berkeley responds by saying that because materialists cannot explain how external bodies would cause our ideas, we don't have good reason to accept the claim that an external world more likely exists than not. I don't think response this is very strong; I think there are strong reasons to believe it is more likely that external things cause our ideas than spirits, even if materialists cannot explain how this could happen.

In this treatise, Berkeley expounds on his theory of immaterialism. This basically states that no material thing exists outside of that which perceives it and bears no relation whatsoever to solipsism—the belief that only the self exists.

This work was the first I'd ever read by George Berkeley.In this treatise, Berkeley expounds on his theory of immaterialism. This basically states that no material thing exists outside of that which perceives it and bears no relation whatsoever to solipsism—the belief that only the self exists.
Berkeley was a deeply religious man who believed that nature and matter did not exist without being perceived in consciousness; that this perception was an idea instilled in the spirits of men through the infinite all-perceiving mind of God. Therefore, the revelation of God as the very originator of creation is available to anyone not bound by the notion of material existence outside of consciousness.
From a materialist, purely Cartesian, Newtonian perspective, his ingenious works might seem ludicrous. There were no physicists at the time to chime in with theories of quantum physics that so readily collapse the foundations of materialism. Berkeley stood his ground alone.
The prose is bloated and bombastic, but let's not forget the text was written in 1710, and compared to other writings of his time, his was simple and straight to the point.
A TREATISE CONCERNING THE PRINCIPLES OF HUMAN KNOWLEDGE is a treasure to anyone with a spiritual or religious inclination. The message is as deep as it is subtle, and can be quite transformative if you allow its transcendental logic the benefit of a truly open mind.

I was taught from a very young age that reality is what exists independently of human perception and knowledge, and we gain knowledge of reality if and only if our ideas correspond to it.

The Meaning of RealityI was taught from a very young age that reality is what exists independently of human perception and knowledge, and we gain knowledge of reality if and only if our ideas correspond to it. Fantasy is that which has no correspondence in reality, and exists only in the mind of an individual -- unless he communicates his fantasy, others have no way of knowing it.
George Berkeley, after whom University of California at Berkeley was named, shows a different way of interpreting reality. He reasons that ideas in the mind can only be derived from ideas in the mind, and not what exists independently of the mind. Therefore, our sense perceptions are signs, not of material substances existing outside the mind, instead, they are signs of ideas which subsist in the mind of God and are communicated to us directly and individually, without "nature" as an intermediary. The "laws of nature" are not attributes of material substances, but attributes of the inter-relations of the divine ideas communicated to us, like the rules of syntax and semantics in the study of language.
Descartes and Berkeley
Descartes is known for the dictum, "I think therefore I am". Berkeley's philosophy can be simplified as, "I think thereby the world exists". Both philosophers converge on one point: "I think therefore God is".
Like Descartes, Berkeley started from meditating within his own mind, and saw that the mind is different in nature from the object it perceives -- the former is active and immortal whereas the latter is not. They both inferred the existence of God, by acknowledging the limitation of their mind -- they can only effect and perceive a very small portion of reality, of which a far superior Mind must be the Author.
Unlike Descartes, Berkeley denies the reality of matter as an inert substrate with the potential to come into existence by participating in forms. To his mind, matter is inconceivable, and what is inconceivable is non-existent by definition. However, he can't explain the fact that others can conceive it. In addition, he admits that he doesn't perceive other minds from the senses, and must infer their existence indirectly by logic. An argument can be made that the existence of matter is inferred indirectly by logic apart from the senses. Personally I think Descartes is the more logically consistent of the two.

George Berkeley's Treatise is largely a response to the intellectual storm stirred up by Locke and Descartes, even quoting Locke on several occasions within the Treatise.Berkeley would be described in current philosophical terms as an idealist. The main purpose of his treatise is to show that we are all spirit and reality does not exist outside our perception of it. The world is sustained by God and the perceptions of men. No objects have an "essence" or even a "substance", they only exist as qualities that we perceive in them.
The world according to Berkeley is very "real" in the sense that it follows natural laws set by God and may be interacted with by other lesser spirits (men) in a consistent manner, but he rejects entirely the notion of matter.
This form of idealism solves many of the tricky philosophical problems with the existence of matter, its interaction with space and time, and the definition of infinitesimals, but I believe it opens up a different (and nastier) can of worms. For example:
"33 ... The ideas imprinted on the Senses by the Author of nature are called REAL THINGS; and those excited in the imagination being less regular, vivid, and constant, are more properly termed IDEAS, or IMAGES OF THINGS, which they copy and represent. But then our sensations, be they never so vivid and distinct, are nevertheless IDEAS, that is, they exist in the mind, or are perceived by it, as truly as the ideas of its own framing. The ideas of Sense are allowed to have more reality in them, that is, to be more STRONG, ORDERLY, and COHERENT than the creatures of the mind; but this is no argument that they exist without the mind. They are also LESS DEPENDENT ON THE SPIRIT, or thinking substance which perceives them, in that the are excited by the will of another and more powerful spirit; yet still they are IDEAS, and certainly no IDEA, whether faint or strong, can exist otherwise than in a mind perceiving it."
"36 ... There are spiritual substances, minds, or human souls, which will or excite ideas in themselves at pleasures; but these are faint, weak, and unsteady in respect of others they perceive by sense -- which, being impressed upon them according to certain rules or laws of nature, speak themselves the effects of a mind more powerful and wise than human spirits. These latter are said to have more REALITY in them than the former: by which is meant that they are more affecting, orderly, and distinct, and that they are not fictions of the mind perceiving them. And in this sense the sun that I see by day is the real sun, and that which I imagine by night is the idea of the former."
If the only difference between reality and imagination is the magnitude of "affection, order, and distinction", then it makes sense based on Berkeley's premises that our ideas are indeed weak reflections of reality. But this is a one-way sieve. It is clearly evident that our momentary experiences are distinct from our mental recall or reconstruction of them, but why can't we simply imagine an experience with enough order and distinction to become reality? Let's suppose that we take a hip new psychedelic and hallucinate a scene vividly with just as much order and distinction as our sober perception of reality. Does it then become "real"? Can we actually create the world around us by willing the alterations of our own perceptions so long as they are orderly and distinct? This is the weak link of Berkeley's treatise, and unfortunately also the foundation on which he builds the rest of his arguments.
Worth the read if you are interested in understanding one of the influential figures of modern idealism.

Which leads to the next question. Dr. Bradatan writes a great Introduction in which he summarizes the question and answer:
If there is no such thing as matter, what is it, then, that we experience in the outside world? It is God's Discourse. The world is living word. In Principles, as well as in most of Berekely's other philosophical works, nature is seen as the "visual language" that God uses to speak with us. The things we see around us, their unfolding and succession, their changing into one another, are not meaningless occurrences, but they form divine speech; they say something about the "Author of Nature." Introduction, Pg. XIII.The world only exists because it is perceived. Not only by us (or more appropriately me, because I can't be sure you exist), but by the Spirit (codename : God) as well. It is the Spirit's act of perception which maintains existence when I am not actively perceiving. It's all very Hindu actually. There's a story in which Vishnu sleeps dreaming of the universe and Brahma sits on a lotus growing from his navel. When Brahma opens his eyes, the world is created and, after millions of years, Brahma blinks and the world is destroyed only to be recreated when Brahma reopens his eyes. Or something close to that. Though I'm sure Berkeley, who was a Bishop in the Anglican Church, would object to the comparison.
Berkeley dispenses with any drawn out methodology underlying his premise that we experience the Idea of things, and not things themselves. Which probably doesn't win any converts to his extreme view of existence. But it's a fascinating way to view the world.

Berkeley's treatise is somewhat of a mixed bag. There are some sensible theses, arguments and conclusions in here, just as there are plenty of hard-to-believe ones(his conclusions mostly), however, all in all his book makes for an interesting read and it definitely has enough shock value to challenge the reader's worldview, which is always a plus for me.A central point of the book — and probably the hardest to sustain — is that all sensible things are actually ideas, ergo their existence depends on the fact that they're perceived by a mind. This is so because we simply cannot think of objects outside of a mind, that is outside the frame of a mental perspective, and this, alongside with the unintelligibility of the way that matter could act upon the spirit to produce ideas, led Berkeley to consider the existence of external objects as something rather ridiculous. A very hard to swallow thesis, with plenty of counter arguments lurking about.
While I disagree with his rebuttal of the external world as, well, external, I think he makes a decent case against the distinction between primary(length, mass, speed etc) and secondary qualities (color, texture etc) concerning concrete objects. It is indeed absurd to think of an object to be a certain object or type of object only on the basis of the so called primary qualities, that only those pertain to the object per se, while the rest are nothing more than a product of our senses. It is absurd precisely because such an object is unthinkable, for all of them qualities are interconnected ontologically to make up an object whatsoever.
Berkeley's little philosophical treatise is a bit dense, but definitely worthwhile to read and meditate upon it, especially as some of his ideas can be given a more contemporary interpretation. Aside of philosophical considerations, his downright superb, concise and bittingly polemic writing style might just be enough sometimes to convince the reader of the justness of his ideas, especially when the arguments kind of fall short.

For what was known at the time, Berkeley's ideas were unorthodox but prescient. The exaggerated claims of knowledge by natural philosophers at the time needed to be brought down. Berkeley assisted. The subjectivity of reality hadn't been fully realized. Berkeley helped us get there. Language matters, Berkeley noticed. Maybe most importantly, Berkeley partially cleared a path of doubt for Hume to later completely doubt.
Nonetheless, Berkeley's philosophy suits his own beliefs too well (infinitely as a useless/chimerical concept, consciousness being an immaterial soul, the existence of an ideal state, the architect of reality as the Catholic God) and doesn't offer the 'clear proof' of god he thinks it does. His clear proof is nullified when the reliability of the ideas inside the human mind are called into question by Hume not too long after.
Berkeley gets three stars (plus a half if it were available) because the work is an enjoyable and thought-provoking classic even if the ideas are dated, and although he helped move us forward, some of his ideas are quite obscurantist in nature meaning I can't fall head over heals for it despite my admiration for many of his thoughts.

Berkeley is basically the 18th century Plato. But not in that he does or develops further some of the interesting things Plato did all those years ago. No. He's the 18th century Plato in that he proves amazingly adept at the straw man fallacy, at what amounts to name-calling, and at being a smug prick who is mostly laughably wrong about everything.But this thing is real entertaining, and Berkeley is adorable when he is complaining about language.
