As John Newman said with respect of definitions of communication: “The diversity and complexity of communication is such that a generally accepted definition becomes so profoundly involved that it hinders rather than helps further thought on the subject.” He proposes picking a meaning (not the meaning) which will permit us to speak intelligibly to one another–and proceed with our research.
