What is noumena?

Noumena is a philosophical term that originates from the work of Immanuel Kant, a key figure in modern philosophy. In Kant's framework, noumena refers to things as they are in themselves, independent of our perception or experience. This contrasts with "phenomena," which are the things we perceive through our senses and understand through experience. In essence, noumena represent the objective reality that exists outside of human perception, while phenomena are the subjective interpretations of that reality as experienced by individuals. Kant argued that while we can have knowledge of phenomena through our sensory experiences, noumena remain fundamentally unknowable because our understanding is always mediated by our senses and mental faculties. This distinction is central to Kant's critique of pure reason and his views on the limits of human understanding.
