Secondly, it means the creation of objects or the pursuit of activities called artificial as opposed to natural; that is to say objects created or activities pursued by human beings consciously free to control their natural impulses and to organize their life in a plan. Thirdly, it means that frame of mind which we call artistic, the frame of mind in which we are aware of beauty.
