任何事物都有自己质的规定及其界限,并在其范围内表现为“既是”和“非是”的对立统一;“是就是,不是就不是”也有自己质的规定及其界限,并非只是纯粹的反辩证法命题;人的主观能动性的发挥就是辩证法和形而上学两极方法交替运用的产物,否则就没有人类对自然的改变和对自己的发展这种主观能动性本身的规定。所以,运用辩证法和形而上学的对立统一进行思考,才能更准确地把握事物的本质及其规律性。 Everything has its own set of rules and its limits, and within its scope, it appears as a unity of opposites of “both” and “not.” “Yes, no, no” has its own rules and boundaries, not just Pure anti-dialectics proposition; man’s subjective initiative to play is the dialectical and metaphysical method of alternating the product of the two poles, otherwise there is no human nature changes and their own development of this subjective initiative itself. Therefore, using the unity of opposites of dialectics and metaphysics can we grasp the essence and regularity of things more accurately.
