邓小平被"打倒"以后刚恢复工作，他曾经明确指出，外行不能领导内行。

那是在七十年代后期，他是负责文教卫和科技的。

胡耀邦、李先念、邓小平、‘彭真’等，他们以“实践是检验真理的唯一标准”否定了“两个凡是”。

随着社会的发展，应该进入更深程度认识真理的阶段。

(English）

 Are there the conflict?

When Deng Xiaoping just restoration his work, he had made it clea that a layman: Amateur cannot lead the experts. 

That was in the late 70s, he was responsible for culture、 education、health and science、 technology.

Hu Yaobang, Li Xiannian, Deng Xiaoping, Peng Zhen,etc, tThey negate "two truths" by "practice is the sole criterion of truth".

With the development of society, we should enter into a deeper understanding of the truth
