If you see graphic design as a process of arranging shapes on a canvas, then you’re only seeing half of what you work with. The negative space of the canvas is just as important as the positive elements that we place on the canvas.
Philosophy of design is the study of assumptions, foundations, and implications of design. The field is defined by an interest in a set of problems, or an interest in central or foundational concerns in design. In addition to these central problems for design as a whole, many philosophers of design consider these problems as they apply to particular disciplines (e.g. philosophy of art).
