berkeley’s idealism Flashcards

1
Q

idealism

A
  • everything that exists is a mind or dependant on a mind
  • ‘to be is to be perceived’
  • the view that there are no mind independent objects
  • this view is anti realist
  • (there are only ideas of trees, not actual trees - mind independent objects don’t exist)

Q

the objects of perception

A
  • what is perceived is perceived immediately
  • the causes of this aren’t themselves perceived but inferred
  • everything that is a quality
  • each sense perceives types of qualities
  • nothing in addition to qualities is perceived
  • Berkeley is saying that qualities are the only thing we truly encounter
  • anything else must be reasoned to, we never perceive it

Q

only qualities are perceived

A
  • each sense perceives types of qualities
  • when we perceive physical objects, we don’t perceive anything in addition to its primary and secondary qualities
  • therefore, everything we perceive is either a primary or a secondary quality
  • both primary and secondary qualities are mind dependent
  • therefore, the objects of perception are entirely mind dependent

Q

only qualities exist

A
  • a ‘material substratum’, if distinct from its primary and secondary qualities, is never perceived
  • it is indescribable and inconceivable
  • nothing in experience supports its existence because we only perceive qualities
  • positing matter leads to scepticism about the world
  • therefore, only qualities exist and not matter

Q

simplicity and empiricism

A
  • idealism can be claimed to be the most simple theory and the one that best respects empiricism
  • there are two kinds of thing we are directly aware of: mind and ideas
  • idealism is simple because it explains everything in terms of the minimum number of kinds of things (indirect realism posits minds, idea and matter)
  • idealism respects empiricism because it doesn’t seek to explain the world in terms of things we don’t have experience of

Q

objection: appeal to the stone

A
  • this is not a serious object, it is a fallacy
  • it is when you reject something merely because it sounds absurd

Q

objection: unpercieved objects don’t exist

A
  • when objects are not being perceived, then they don’t exist
  • I still exist even when no one is perceiving me

Q

response of the objection that unperceived objects don’t exist

A
  • objects exist in the mind of god and are therefore always being perceived
  • ideas we perceive are not just caused by god’s mind, but exist in god’s mind (though not perceived by god)

Q

objection: on god
(idealism)

A
  • the existence and role of god is not assumed but reached by argument
  • what I perceive is in my mind, not god’s mind
  • god can’t have the sort of perceptual experiences I have
  • god doesn’t perceive as I do, and doesn’t undergo sensations (eg pain)
  • the ordinary objects of my perception change and go out of existence, but god’s mind is said to be unchanging and eternal
  • therefore, what I perceive count be part of god’s mind

Q

response to the objection on god

A
  • what I perceive is a copy of the idea in god’s mind
  • the ideas of physical objects exist in god’s mind not as perceptions but as part of god’s understanding
  • so, while god doesn’t feel pain, he knows what it is for us to feel pain
  • what I perceive, which changes, is what god wills me to perceive and ‘things …may properly be said to begin their existence…when god decreed they should become perceptible to intelligent creatures.’
  • the whole of creation exists in god’s mind, eternally

Q

objection: illusions
(idealism)

A
  • we perceive ideas, therefore there must be an idea that corresponds to the illusion
  • eg if we perceive a pencil that is crooked, then there must be a crooked pencil
  • the idealist can’t claim our perception is misleading because (according to the idealist), the perception is all there is
  • it follows that there is a distinction between appearance and reality so, it is not the case that to be is to be perceived and therefore idealism is false
  • idealism fails in its claim that to be is to be perceived, which means it is not the case that the objects of perception are mind-dependent ideas

Q

response to the illusions objection
(idealism)

A
  • illusions are real but misleading
  • we aren’t misperceiving in an illusion (eg the pencil really is crooked)
  • but this is not typical circumstances, so we can easily be misled
  • (eg) the pencil would not appear crooked if we took it out of the water; the pencil would not feel crooked
  • the correct this we should say that the pencil looks crooked
  • Berkeley denies the inference from the stick looking bent to the claim that the stick really is straight
  • this is a confusion over what Berkeley meant by ‘to be is to be perceived’; to be bent is merely to look bent, not to possess a quality of bentness

Q

objection: hallucinations

A
  • Berkeley distinguishes imagination from perception because imagination is in our control but perception isn’t
  • hallucinations are not in our control so what distinguishes the from perception

Q

response to the hallucinations objection

A
  • hallucinations are not always in our control but are caused by our minds (unlike perception)
  • hallucinations can sometimes be identified because they dim, irregular and confused
  • they do not cohere with the rest of nature
  • hallucinations lack logical connection to the rest of our experience; however, this response is unsuccessful because some hallucinations might be logically connected to the rest of our experience (e.g if you have a fever dream)

Q

objection: solipsism

A
  • solipsism is the view that only oneself, one’s mind exists
  • if everything that I perceive is mind dependent, do I have any reason to think that anything exists apart from my mind
  • does anything exist apart from ideas, does my mind exist as a thing
17
Q

response to solipsism objection

A
  • the mind is that which actively perceives, thinks and wills while ideas are passive
  • I am aware of myself as capable of this activity
  • therefore, I am not my ideas but a mind
  • being a mind myself, I have a notion of what a mind is
  • therefore, it is possible that other minds exist
  • my perceptions don’t originate in my mind
  • therefore, they are caused by some other mind
  • the complexity and regularity of my experience indicates that this mind is god
  • I can also infer form experience that other minds exist
18
Q

Berkeley’s three main arguments

A
  1. mind dependent ideas can’t be like mind independent ideas
  2. objection to the primary/secondary distinction
  3. the ‘master’ argument - we cannot even conceive of mind independent objects
19
Q

the attack on Locke’s primary/secondary distinction

A
  • Berkeley argues that the only thing our senses perceive are qualities, and nothing more
  • but, we never perceive anything in addition to these qualities
  • this claim forms the basis of one of Berkeley’s arguments against the existence of a mind independent external world
  • Locke and Berkeley claims that secondary qualities are mind dependent
  • Locke claims that primary qualities are mind independent, Berkeley disagrees
  • Berkeley offers various versions of perceptual variation to support the claim that primary qualities depend on the mind just as much as secondary qualities do, e.g something that looks small to me may seem large to a small animal
  • size, shape, and motion are all primary qualities and the example shows how our perception of them differs depending on the circumstances
  • so, Berkeley argues, we can’t say these objects have one single size, shape, or motion independent of how it is perceived
  • therefore, primary qualities are also mind-dependent
20
Q

Berkeley’s argument attacking Locke summarised

A
  • when we perceive an object, we don’t perceive anything in addition to its primary and secondary qualities
  • everything we perceive is either a primary quality or a secondary quality
  • secondary qualities are mind-dependent
  • primary qualities are also mind-dependent
  • therefore, everything we perceive is mind-dependent
  • Berkeley uses Locke’s primary and secondary quality distinction to prove that everything we perceive is mind-dependent
  • this implies that there is no such thing as a mind independent external world (and so realism is false)
21
Q

the master argument

A
  • we cannot even conceive of a mind-independent object because as soon as we conceive of such an object, it becomes mind-dependent; thus, mind-independent objects are impossible
  • e.g. you can’t conceive of a tree without a mind to perceive it, because as soon as you do, you must be thinking about that very tree
22
Q

a response to the master argument

A
  • the conclusion does not necessarily follow: just because it’s impossible to have an idea of a mind independent object, it doesn’t mean that mind-independent objects are themselves impossible
  • this confuses our thoughts with the content of our thoughts; can you imagine a world in which you don’t exist
  • response: Berkeley is arguing that we can’t conceive of any un perceived tree because that will always be formed of perceived ideas
23
Q

God as the cause of perceptions

A

there are three options about where our ideas come from:
1. other ideas
2. our own minds
3. some other mind
- no 1 is ruled out because ideas don’t cause anything
- no 2 is ruled out because I am not in control of them
- therefore, ideas must come from another mind
- given the complexity and systematicity, we see that mind must be wise and benevolent beyond measure
- therefore, that mind is god

24
Q

the role of God in indirect realism

A
  • the role of God here resolves an obvious objection to idealism: If Berkeley’s theory is true, then objects no longer exist when not being perceived, so why are they still there - Berkeley’s response is that all physical objects constantly exist in the mind of God
  • what we perceive, Berkeley says, are copies of ideas that exist eternally in God’s mind (when He wills me to perceive them)
  • this resolves another potential criticism: we might object that when two people both look at the same tree, we are perceiving different things – i.e. two separate ideas
  • however, since they are both perceiving the same copy of God’s idea, they can be said to be perceiving the same thing
