Have knowledge ignorance -

 Ancient Greek mathematician and philosopher Zeno (Zeno, about 490 BC ~ 425 BC) Aristotle was hailed as the inventor of dialectic. Once, Zeno and his students,UGG boots, said: We face ignorance. circle the circumference of the larger surface of contact with the more ignorant. It just do science, circle shrink to points, the smallest face of ignorance it?

course not. If such was so understood,bailey UGG boots, can only be considered to be self-deceiving. The accumulation of human knowledge, the development of science is an objective,UGG shoes, not because someone or the knowledge of survival.

Zeno to consider that this is the conversation as a teacher and students, we contacted the ancient Chinese and can also reflexive; known difficulties, and then to self also. ~ 1464) is more profound discussion. Nicholas of Cusa Squaring the circle in the problem (ie only non-scale ruler and compass to make a square, to an area equal to the given area of a circle), the did a lot of trying, without success, so he Reflection: It is not based on ruler and compasses, always only approximate conversion of the circle and square, but not accurate results. Squaring the circle is not an impossible problem?

Although Nicholas of Cusa and many mathematicians, the problem of the circle as neither side can prove that, we can not permit any, but his inspiration this: If the truth is round compared It is fully perfect. The limited capacity of human thinking is not complete, like a series of increasing the number of edges of polygons. Since there can be no non-circular area of a circle to the public what degree, then the limited thinking can not fully know the truth. The more a man knows, the more aware of their ignorance, which is People of this However, even infinitely many regular polygon edges, we can not say that a regular polygon is equivalent to a circle, unless it is a real change in the nature of a circle. Similarly, even if unlimited development of the human mind can not be said to have fully mastered the truth.

this way, Nicholas of Cusa, by analogy,UGG boots cheap, see the limitations of human knowledge and use it as a starting point, write the masterpieces as
