Mastery of skills, or practical knowledge, is of critical importance in the self-identity of man and, indeed, is a cornerstone of civilization. The mastery of skills allows us to create, innovate and achieve in our rapidly changing society. The creation of both tools and objects of art is one of the differentiating factors between humans and animals. Sure, there are some animals that create limited tools or works of art, but there is a clear difference in the human scope of creation. For example, in nature, specific ‘tasks’ may be passed down or the ‘art’ that the rare animal may create is biologically driven and usually just a display for the mating process. The art and tools produced by man are far more diverse and complex than anything you will find in the animal kingdom, owing to man’s rational thought and individual choice.
