If I were to tell you something, wholly based on my senses perhaps it would be that before me is a car, but who knows whether it exists, or whether it is instead a figment of my imagination, or worse still the fabrication of a malevolent deamon, who has placed before me the image of a car to misdirect me. Under such a circumstance, we might ask; why would it do such a thing, can we assign it motivation? Purpose? Can we continue with our lives knowing that nothing before us may be real?
The car appears to be red, but what do we understand by the colour red? Can red be corroborated by others? Do they see what we see? Red is an arbitrary assignment of a particular lightwave reflection, but when does red end and pink begin? The object itself has no colour, it reflects light at a certain wavelength and thus it is our own senses which assign it colour. Thus, is our world a construct of our own mind, how much do we fabricate and how much is derived from reality?
That's how a philosophy student says it, homey.
Edit:- I am also a literature student so....
I want you to imagine that my car is before you, this car is red. Now, let's analyse this in more detail. Saying that it is my car implies a concept of ownership, perhaps then we can infer that I come from a society where this concept is widely agreed upon. Further, we can assert certain things about my character from the fact I own this car, that it is red. I am well enough off, or indeed I have parents with the capictiy to buy it. Further, it is red, now, perhaps I chose this colour to predispose you to my agressive masculinity, the redness a bold, unreserved colour indicating my unashamed manner.
Going deeper, perhaps we could claim that this "redness" is infact a metaphor for blood. Within this context it is certainly indicated to be "my" blood, but does that mean that I am dangerous? Is it a representation of imperialism? The dominance of the rich over the poor? Perhaps even we could assert an analogue to menstrual blood, indicating themes of virginity, virility and the taking of something. Indeed, this is further reinforced by the original concept of ownership, in "taking" it implies that there was something that was originally owned by someone, appropriated by me.
I could go on... and on.... and on... I have to fill 2000 words alot.
