Difference between locke and berkeley relativity of perception

Locke argued that the mind does not have innate ideas and so sensory knowledge is the only knowledge we can have. This view is known as empiricism. Locke claimed that if we had innate ideas - knowledge that does not come from experience - then all beings that possess a mind should be aware of them. Even if we could find some rational knowledge that everyone is aware of possessing, then Locke claimed this would still not show that we have come to know these ideas innately and not through shared experiences.

Locke argued that we have two types of experiences: We gain some knowledge from reflection, some from sensation, and some from both. Reflection allows us to be conscious of our mental processes, and so tells us about how our minds operate. Locke described two types of sensations: Primary qualities are similar to the properties Descartes equated with rational introspection, such as size, shape, and quantity.

Secondary qualities correspond to qualia, like colour, sound, and emotion. Locke highlighted the problem of secondary qualities with his example of the inverted spectrum.

Instead, Locke advocated causal realism, the view that we can at least derive the existence of external objects from the qualia they invoke in us. We cannot know if these objects really resemble the qualia they invoke. Berkeley argued that causal realism is inconsistent with empiricism.

  1. Before Kant, both empiricists and rationalists had accepted that rationalism could only explain analytic knowledge. These are contrasted with synthetic statements, statements that provide information about the world.
  2. They are not learned from experience.

Yet the brain only has access to the final stage, the qualia. Berkeley showed that if secondary qualities exist in the mind then primary qualities must also exist there, as we cannot imagine them devoid of qualia: He went on to suggest that this must also be true of mass and numbers. We say one book, one page, one line, etc. Because everything that we experience originates in the mind, Berkeley claimed that the only theory available to empiricists is idealism, the view that physical objects do not exist.

Quantum computers and artificial realities Quantum computers All computers can be described as Turing machines, a concept devised by British mathematician Alan Turing in 1936. Physicist Paul Benioff first considered a quantum Turing machine in 1981, [6] and, in 1985, Deutsch showed how this could be done.

A quantum computer can store information in a superpositional state, and hence perform more than one calculation at once. In 1999, physicists at IBM developed a 3-qubit quantum computer where a qubit, or quantum bit, is a unit of quantum information and by 2001, they had developed a 7-qubit computer that could be used to calculate prime factors.

This leads back to the philosophical question of whether we could be living inside of a simulation. Human consciousness is predicted to require about 1016 - 1017 10-100 million, billion operations per second and Bostrom predicted that it would take about 1033 - 1036 1-1000 million, billion, billion, billion operations per second in order to simulate our current experience of the universe.

In 1992, American engineer Kim Eric Drexler showed that a system the size of a sugar cube could perform 1021 1000 billion, billion operations per second, [12] and, in 2001, computer scientist Robert Bradbury showed that a computer with a mass similar to that of a large planet could perform 1042 a million, billion, billion, billion, billion operations per second.

The further back you go, the more likely it is that they would be wrong. Instead, he remained just as sceptical about the existence of the mind. In An Enquiry Concerning Human Understanding Hume argued that innate ideas, like those found in mathematics, do not tell us anything useful about the external world.

All useful knowledge comes from the qualia we experience, but these do not tell us anything that is necessarily true. Hume stated that qualia make little sense to us until our minds have learned to interpret them, and that interpretations occur by custom, instinct, and habit; if we experience two events in succession enough times, then we will come to expect one event after witnessing the other. The branch of philosophy concerned with what we can know is known as epistemology. Hume applied his reasoning to science and argued that we only assume the future will resemble the past, and that the laws of physics will not suddenly change, because this is how the world has always appeared to us.

Domestic animals expect food when they see the person who feeds them. We know that all these rather crude expectations of uniformity are liable to be misleading. The [person] who has fed difference between locke and berkeley relativity of perception chicken every day throughout its life at last wrings its neck instead, showing that more refined views as to the uniformity of nature would have been useful to the chicken.

The mere fact that something has happened a certain number of times causes animals and [people] to expect that it will happen again. He could not see any evidence that the mind is made of a non-physical substance, or that it persists through time separately from the body. In a similar fashion, Hume did not think that there was any evidence of God. Like English philosopher Thomas Hobbes, he did not think that the mind could conceive of such an entity.

Before Kant, both empiricists and rationalists had accepted that rationalism could only explain analytic knowledge. Analytic knowledge derives from statements that are true by definition.

This is because being a flower is part of the definition of being a daisy, and having three sides is part of the definition of being a triangle. These are contrasted with synthetic statements, statements that provide information about the world. It was believed that synthetic knowledge could only be known from experience; however, Kant argued that that this is false. Kant claimed that this means our knowledge of mathematics comes from an innate knowledge of the external world.

Kant argued that aside from rationalist synthetic knowledge, the only way to gain information is through analytic statements, which are entirely empirical. Kant claimed that the mind is needed in order to make sense of the continuous stream of qualia that we perceive. He claimed that external objects exist outside of time and space, and that the mind is needed to organise qualia into separate spatial and temporal locations.

Berkeley v. Locke on Primary Qualities

This means that the concepts of space and time are rationalist in nature. They are not learned from experience.

The mind is also needed to join associated qualia into the objects we recognise. In order to do this, Kant agreed with Descartes when he stated that the mind must necessarily be a unified whole.

Kant did not accept mind-body dualism however, because the idea of the soul is also formed by custom, instinct, and habit.

Kant stated that the mind is really just a complex set of abilities, or functions, without a subject:
