"Phenomenology is a school of philosophy whose principal purpose is to study the phenomena, or appearances, of human
experience while attempting to suspend all consideration of their objective reality or subjective association. The phenomena
studied are those experienced in various acts of consciousness, mainly cognitive or perceptual acts, but also in such acts as
valuation and aesthetic appreciation". - Grolier Encyclopedia
