The Experience is the source of all knowledge. By experience I mean sensation from the senses. The five basic senses are the eyes, ears, skin, nose, and tongue, in the modes of sight, sound, touch, smell, and taste respectively. Perception is also part of experience. Perception is the interpretation of the physical data from the senses and also the interpretation of the concepts (mental data). Conceptualisation is a part of this experience. It is the accumulation of concepts – physical and mental data – that I term knowledge. Signification (language) is the part of this experience of this particular animal.
Without sensory experience we do not have knowledge. The beginning of sensory experience is what we call life, and its end is death. Everything in between is The Experience.
