An object or entity can be said to have certain properties, eg height, mass, position etc. But does the object exist independantly and beyond these properties, or is a set of properties all that can be said to exist? If we try to imagine what an object is actually like without the distortions it goes through from object to observer (our senses and consciousness may show a very different picture from the reality) all we are left with is a set of properties. Colours are simply different wavelengths of light being absorbed and reflected, and even things such as shape may be an invention of our consciousness to help us to understand our surroundings (a square will always have four equal sides and angles but what we see when we look at a square is invented). So is there more to an object's existence than a set of properties? If not, what is it that has these properties?
