An amateur is generally considered a person who pursues a particular activity or field of study independently from their source of income. Amateurs and their pursuits are also described as popular, informal, self-taught, user-generated, DIY, and hobbyist.
History
Historically, the amateur was considered to be the ideal balance between pure intent, open mind, and the interest or passion for a subject. That ideology spanned many different fields of interest. It may have its roots in the ancient Greek philosophy of amateur athletes competing in the Olympics. The ancient Greek citizens spent most of their time in other pursuits, but competed according to their natural talents and abilities. The "gentleman amateur" was a phenomenon among the gentry of Great Britain from the 17th century until the 20th century. With the start of the Age of Reason, with people thinking more about how the world works around them,, things like the Cabinet of Curiosities, and the writing of the book The Christian Virtuoso, started to shape the idea of the gentleman amateur. He was vastly interested in a particular topic, and studied, observed, and collected things and information on his topic of choice. The Royal Society in Great Britain was generally composed of these "gentleman amateurs", and is one the reasons science today exists the way it does. A few examples of these gentleman amateurs are Francis Bacon, Isaac Newton, and Sir Robert Cotton, 1st Baronet, of Connington. Amateurism can be seen in both a negative and positive light. Since amateurs often lack formal training, some amateur work may be considered sub-par. For example, amateur athletes in sports such as basketball, baseball, or football are regarded as possessing a lower level of ability than professional athletes. On the other hand, an amateur may be in a position to approach a subject with an open mind and in a financially disinterested manner. An amateur who dabbles in a field out of interest rather than as a profession, or possesses a general but superficial interest in any art or a branch of knowledge, is often referred to as a.
Amateur athletics
The line between amateur and professional has always been blurred in athletics with the central idea being that amateurs should not receive material reward for taking part in sports. The lack of financial benefit can be seen as a sign of commitment to a sport; until the 1970s the Olympic rules required that competitors be amateurs. Receiving payment to participate in an event disqualified an athlete from that event, as in the case of Jim Thorpe. The only Olympic events that still require participants to be amateurs are boxing, wrestling and figure skating but amateurism in these cases is defined in terms of rules, mainly participation in "professional events", rather than whether the athlete receives any money for his sport.
