The big questions: epistemology
What is the nature of our knowledge about our existence, environment and relationship toward it? What is the nature of our methods for gaining knowledge? How does reality relate to the representation which is created in our speech, images, sounds, imaginations, mental reflections or visualisations? What is the function of symbols, metaphors, which imagine and create similarities, and their meaning?
These meanings about reality, which is assumed to be constant, vary from individual to individual and from minute to minute. They depend on our culture, interests and situations, particularly in our present day, when everything is mapped and mediated through information devices.
