This document discusses common sense from philosophical and scientific perspectives. Philosophically, Plato saw common sense as an intuitive aspect of knowing, while modern thinkers like Descartes questioned intuitive certainty. Scientifically, Aristotle viewed science as moving from sensory experiences to general principles, while later scientists like Galileo and Newton took a more mechanistic view. In management theory, thinkers like Barnard, Simon, and Patton advocate balancing analysis and intuition, or common sense, in decision making. While common sense can hinder innovative thinking, it remains an important element in management if understood as basic intuitive truths and principles.
