Representative Realism is a philosophical concept, largely developed by Bertrand Russell. It does, unlike naïve realism, take into account sense data (the way in which the object is interpreted, not simply the objective, mathematical object) - this induces the veil of perception wherein we are unsure the table we look at exists due to there being no objective proof of its existence. In other word, the table at which I look looks a particular shape to me, due to the angle of vision, and a particular colour due to the way in which the light bounces off it - this is different to the table at which the person next to me sees.
