Assess representative realism.

Introduction

Assess Representative Realism [24] Representative Realism (like direct realism) states that the world consists of material objects that occupy space, and that these material objects possess properties that exist independently of a perceiver. However, unlike the direct realist, the representative realist would claim that we cannot directly perceive objects as they really are, independent of us. The representative realist distinguishes sense data from the objects perceived and that the physical object causes a sensation in us (a representation of the object as it is). Only objects that possess primary qualities (occupation of space, motion etc) exist independently of us. Sense experience of colour, sound, smell and taste do not exist in the objects themselves in the same way that the primary qualities do. ...read more.

Middle

Another example would be when we consider an object like an apple. We are still able to recognise that an apple is an apple, regardless of whether or not we can see its colour or be able to smell it or hear it. So it is obvious that these qualities are not the essential properties of an apple. However, we are unable to imagine an apple that is devoid of any shape, size, position or motion, which would lead us to conclude that these are the essential properties of an apple. We can only learn about physical objects through the observation of the primary qualities in our sense data, and as long as we are able to recognise which aspects of our sense data are accurate representations of the external world, we can build an accurate picture of it. ...read more.

Conclusion

How do we know how accurate our representation of the real world is? Everything we perceive must come from our five senses, which would lead us to conclude that only the secondary qualities can be perceived directly, and not the primary qualities. If the existence of physical objects (possessing primary qualities) is simply inferred from our senses, how can we be sure that our senses are accurate in their representation? Without independent access to the real world, we cannot make comparisons between our sense data and the physical objects that they represent. We are not able to establish when we are being deceived, or what the world consists of, or even if it exists it all. Thus representative realism fails to explain how we come to have knowledge of the world, or even if it is possible. ...read more.

  2. Outline and assess the main objections to representative realism

    Although individual hallucinations can be pointed out by the indication of others, there is a much more problematic issue of general or widespread misrepresentations. However, one reply to this objection is that the existence of the external world is a plausible hypothesis.
