UniversalismUniversalism is the belief that there are truths that can be applied to the entire universe and in every situation.
RelativismRelativism is the belief that truth is entirely subjective and individual and that each individual is justified in demanding others recognize their view of reality. Relativism is embraced by postmodernism.
PragmatismPragmatism is the view that it doesn't matter if something is universally true as long as it is true for all practical purposes in a situation. Pragmatists also view subjective reality as meaningless unless it has some type of practical application.
MaterialismMaterialism is the belief that all things including complex intangible things such as imagination have a physical basis.
IdealismIdealism is the belief that all things or some things are immaterial such that they have no physical form. This is pragmatic as the human experience and modern economic production are often based on intangible things. For example, a video game may be based on physical things such as electrons but its value is completely derived from intangibles such as art, experience, story, characters, fashion, language, symbols, social status, emotion and risk.
RealismRealism is the idea that reality often differs from our perception as the later is shaped by our ideas, emotions, senses and cognitive characteristics. For example, color perception greatly differs from the physical properties of light.
SkepticismSkepticism is a general doubt that humans can understand anything about reality beginning with the question of whether our senses are accurate. For example, the possibility that everything that we see is simulated or imagined. Skepticism may question basic human assumptions such as the concept of time and space. The only thing that can be proven under skepticism is existence itself. This is based on the thought experiment "I think, therefore i am" whereby the very act of questioning existence is proof that you exist.
Virtual RealityVirtual reality is an electronically generated environment that fools the senses into thinking that products of imagination are physical realities.
Mixed RealityMixed reality is the integration of the physical world and virtual reality such that virtual things can be sensed in the real world and vice versa.
