"Science has its inception in a participating person who is pursuing aims, values, purposes which have personal and subjective meaning for him. … he immerses himself in the relevant experience… He senses the field in which he is interested, he lives it. Out of this complete subjective immersion comes a creative forming, a sense of direction, a vague formulation of relationships hitherto unrecognized. … It is indeed the matrix of immediate personal, subjective experience that all science, and each individual scientific research has its origin."
