Harish-Chandra made the following remark: "Theoretical physics is in such a mess, I have

"I have often pondered over the roles of knowledge or experience, on the one hand, and imagination or intuition, on the other, in the process of discovery.

Therefore, a certain naivete, unburdened by conventional wisdom, can sometimes be a positive asset."
