In this concept, shi (势) means how things exist, change and evolve, which is objective and primary; and li (利) is the goal set by people, which is subjective and secondary. A goal should be reached through interactions between the objective and the subjective, not by imposing subjective desire on the objective. As the initiator of action, people must continuously try to achieve alignment between the objective and the subjective. In this way they will rationalize their knowledge, develop a broad perspective and make timely adjustments, which will lead to new discoveries, innovations and advancement. This is the relationship between the objective and the subjective.
