Self or no-self?

Over at the Dharma Overground community, a member started a thread by posing the following question: how to investigate no-self? For serious meditation practitioners who may have encountered this question before or may have reflected on the same, it poses an “enigma”, if you will. One of the members, haquan, from the same community responded by setting up an illuminating dialectic, a sort of a koan.

David Hume criticized those thinkers who claimed that there was no self, saying “They are like the man that leaves his study, goes outside to look through the window, and concludes that he is not home.”
My counter (haquan): “Those who claim there is a self are like someone who leaves his study, goes outside to look through the window, and points to the desk and empty chair saying “See – there I am!”"

Now does the self exist or not? How can the man investigate it when he can not see himself, and has no mirror?

There is only the field of experience.
