Or so I have interpreted it.
What I have to add to this is that once a writer as described above is identified, his or her writings also become an invaluable source of ideas about how to further ourselves along the lines of our, now shared, beliefs. So, not only do we find in others' writings a blueprint to our own minds as we find them at the time, but also a blueprint to a possible extension. Or even a nice gazebo. And so on.
Or so I have always felt myself.
