Discovery, not dissertation

In text describing his departure from the Village Voice, political columnist Wayne Barrett wrote:

My credo has always been that the only reason readers come back to you again and again over decades is because of what you unearth for them, and that the joy of our profession is discovery, not dissertation.

Barrett also asserted:

There is also no other job where you get paid to tell the truth.

One might say that patent attorneys and agents are paid to write the truth, about things that are novel and useful.

One might say that patent attorneys describe invention, not dissertation. One does not need to give details about "why" something works, but it is necessary to enable the practice of the invention.
