It is important to note that science is based on proven truth; therefore it is knowledge by description.

However the profound knowledge within the arts, the evocation of feeling, is not knowledge by description, the justified true belief of Plato. In fact, Plato was hostile to arts in general. For him it was a rival to the pursuit of truth and had the potential to corrupt and "upset". For pragmatic Plato, art often went against all principles of natural science. Example of this is portrayed in Oscar Reutersvard's work of art, which is a tangential image of the natural world. Swedish artist Oscar Reutersvard is the "father of impossible figures." He was the first to deliberately make impossible figures (previously they occurred in artwork unintentionally due to lack of perspective skill). In 1934 he created the first impossible triangle out of a series of cubes (shown below). Here he creates a shape, which is physically impossible to create in the three-dimension world as the triangle/cube meets in an impossible configuration. Despite this, based on our visual system, the triangle formed by 9 cubes appears to move away and come towards us. This image of illusion is also illustrated in the impossible staircase, developed by Lionel Penrose (shown on next page).

Although the actual model is separated at the right stair, we can't see the split, because our visual system assumes that it is seeing this model from a non-accidental point of view; hence, it assumes that the stairs are joined. Although the staircase is conceptually impossible, it does not interfere with our perception of it. In fact, this physical impossibility is often not apparent to most people. Therefore these disturbing images supports Braque's view on art and it is only through scientific theories which proves the impossibilities of these dimensions, which informs architectures on what design is physically possible to build in our environment.
