Contradicting views and ideas could aware us of the mistakes and flaws in our work which we can not discover by ourselves， bring us fresh angles and perspectives， and then make our work mature and complete. Thereby through the discussion and competition both we and the people disagree with us could make advancements in our learning. Debate on the same subject make it possible for human beings to make most of the achievements and advances on fields of science， technology， philosophy and the like. If we see only on the one side of the coin， we could get only a partial and distorted knowledge and view which might mislead our learning.
Also， contradiction may cause negative effects under certain conditions， especially when the debate becomes irrational denouncement or personal attack. Then our confidence would be impaired by the criticisms and our learning inhibited by the stress excessive contradictions brings us. Disagreements would be detrimental rather than beneficial to our learning under this circumstance.
Bias on each of the two sides is detrimental to our learning for that agreements and disagreements form a organic entity which can not be absolutely divided. Over reliance on one side is blind and unwise. Agreements base on no evidence are actually flatters; disagreements without rational reasons are reprimands. We would be enmeshed in the web of self-contention sewed by ourselves and could not go ahead if we and blinded by the flatters; we would be frozen in the chilly night of darkness created by reprimands and became helpless and hopeless. We must pay equal attentions on both sides to see the whole picture.
To sum up， ideas of people whose views we share and people whose views contradict our own play their respective role in our learning， and none of them should be neglected. Therefore， balance between both sides is needed. And only through this way could we achieve the further goal in our process of learning.
