A college student was in a philosophy class which had a discussion about God’s existence.The professor presented the following logic¹:

大学生们在上哲学课，讨论上帝是否存在的问题。教授给出了下面的逻辑推理:

"Has anyone in this class heard Gods Nobody spoke².

“班上有谁听见过上帝吗?”没人说话。

"Has anyone in this class touched God?”Again nobody spoke.

“班上有谁触摸过上帝吗?”还是没有人说话。

"Has anyone in this class seen God?"When nobody spoke for the hird time，he simply stated，"Then there is no God.”

“班上有谁看见过上帝吗?”当第三次还是没有人说话时，教授就说:“所以，上帝是不存在的。”

One student thought for a second，and then asked for permission to reply. Curious to hear this bold student’s response，the professor granted it，and the student stood up and asked the following questions of his classmates:

一名学生思考了一下，要求回答问题。教授很好奇，想知道这个大胆的学生有什么反应，就同意了。学生站了起来，问了他的同学下面几个问题:

"Has anyone in this class heard our professor's brain?"Silence.

“班上有谁听见过我们教授的脑子吗?”沉默。

"Has anyone in this class seen our professor's brain?”Silence.

“班上有谁触摸过我们教授的脑子吗?”沉默。

When nobody in the class dared to speak，the student concluded，"Then，according to our professor’s logic，it must be true that our professor has no brain !”

班上没有人敢说话，这名学生总结道:“所以，根据我们教授的逻辑，我们的教授一定没有脑子。”
