A man may have intelligence enough to excel in a particular thing and lecture on it, and yet not have sense enough to know he ought to be silent on some other subject of which he has but a slight knowledge; if such an illustrious man ventures beyond the bounds of his capacity, he loses his way and talks like a fool.
But we should ask the question: Why should a writer be more than a writer? Why should a writer be a guru? Why are we supposed to be psychiatrists? Isn't it enough to write and tell the truth? It's not like telling the truth is common. Writers are the earthworms of society. We aerate the soil. That's enough.
