Final answer:
The phrase 'He becomes an appendage of the machine' is commonly associated with discussions on the industrialization of society and how technology affects human identity, which could be attributed to thinkers or artists such as Karl Marx or Francis Picabia.
Step-by-step explanation:
According to the naturalist mosaic, the quote “He becomes an appendage of the machine” reflects the Naturalist perspective on the impact of industrialization and mechanization on humanity. This view can be associated with a variety of thinkers and artists during the industrial age, such as Karl Marx, who critiqued the dehumanizing effects of the factory system on workers or artists like Francis Picabia and Jean Tinguely who expressed these themes through their mechanomorphic artworks. The quote epitomizes the concerns over the loss of individuality and the transformation of human beings into components of the industrial machinery they operated.
These themes are also reminiscent of the sentiments of artists and social critics during the early 20th century. Notably, the Futurists, such as Umberto Boccioni, celebrated the bond between humans and machines, yet their works often grappled implicitly with the consequences of such a fusion. On a broader scale, philosophical reflection upon technology and its influence on humanity has been a recurring theme through history, underlined in works like Leo Marx's “The Machine in the Garden,” which examines the relationship between technology and pastoral idealism in America.
