“I also believe that Spinoza, like Nietzsche and Schopenhauer, on whose lives and philosophy I have based two earlier novels, wrote much that is highly relevant to my field of psychiatry and psychotherapy—for example, that ideas, thoughts, and feelings are caused by previous experiences, that passions may be studied dispassionately, that understanding leads to transcendence—and I wished to celebrate his contributions through a novel of ideas.”

“I wrote my first novel because I wanted to read it.”

“How I wish I lived in a Jane Austen novel!”

“I think it was the ability of the theater to communicate ideas and extol virtues that drew me to it. And also I was, and remain, fascinated by the idea of an audience as a community of people who gather willingly to bear witness. A novelist writes a novel and people read it. But reading is a solitary act. While it may elicit a varied and personal response, the communal nature of the audience is like having five hundred people read your novel and respond to it at the same time. I find that thrilling.”

“For me [fiction] is a manner of philosophizing … Philosophy may be only a shadow of the reality it tries to grasp, but the novel is altogether more satisfactory. I am almost tempted to say that no philosopher is qualified to do his job unless he is also a novelist … I would certainly exchange any of the works of Whitehead or Wittgenstein for the novels they ought to have written.”

“The philosophy of Kant's great successors was consciously a synthesis of Spinoza's and Kant's philosophies. Spinoza's characteristic contribution to this synthesis was a novel conception of God. He thus showed the way toward a new religion or religiousness which was to inspire a wholly new kind of society, a new kind of Church.”

“You know what I did after I wrote my first novel? I shut up and wrote twenty-three more."

“All this sitting about in cafés to calm down
Simply wears me out. And their idea of literature!
The idiotic cut of the stanzas; the novels, full up, gross.

I have lived it, and I know too much.
My café nerves are breaking me
With black, exhausting information.”

“The only time I've ever learned anything from a review was when John Lanchester wrote a piece in the Guardian about my second novel, The Heather Blazing. He said that, together with the previous novel, it represented a diptych about the aftermath of Irish independence. I simply hadn't known that – and I loved the grandeur of the word "diptych."”

“Someone once wrote that a novel should deliver a series of small astonishments. I get the same thing spending an hour with you.

Also, here is a green toothbrush tied in a ribbon. It expresses my feelings inadequately.”
