Final answer:
Jose de Rivera's sculpture 'Infinity' is non-objective because it lacks recognizable subject matter, focusing instead on abstract shapes and forms. The sculpture represents the concept of non-representational art, where aesthetic experience is paramount.
Step-by-step explanation:
Jose de Rivera's sculpture 'Infinity' is considered non-objective because it does not depict recognizable objects from the observable world. Non-objective art does not attempt to directly represent reality but rather focuses on the use of form and color to create a visual language. The purpose of such art is to present compositions that are appreciated for their aesthetic qualities and the emotions they evoke, rather than for their representation of any specific subject matter.
The term 'non-representational' is synonymous with non-objective and applies to art that doesn't recreate or portray identifiable objects or scenes. Rivera's 'Infinity' sculpture, like other non-representational art, invites viewers to engage with it on a level beyond traditional representation, often prompting a contemplation of form and abstract concepts. It is important to note that while 'Infinity' is indeed a three-dimensional object, its three-dimensionality isn’t what makes it non-objective; rather, its lack of recognizable subject matter does.
