Last year, Theatre J sold out its run of New Jerusalem: The Interrogation of Baruch de Spinoza, so if you’re in the DC area and I didn’t successfully drag you to the show this past Wednesday, you had best get your tickets soon. The play is inspired by the excommunication of Baruch Spinoza by his synagogue and spins out a confrontation between him, a Christian official of Amesterdam, and his beloved rabbi and mentor.
In the play, Spinoza is still refining his philosophy. The cross-examination lets the audience see his ideas and their implications get drawn out and developed. But what serves the audience well in the context of a performance may not correspond to the best way Spinoza could have shared his ideas with his friends. He is thinking out loud in front of the entire congregation, many of whom do not have a philosophical background.
In my college debating group, it wasn’t uncommon for people to ‘break’ on the floor — i.e. for a line of questioning to catch a speaker in paradox and force him or her to admit that they had to give up at least part (or possibly all) of their philosophy. But when you brought someone up to the edge of the abyss, it was only good manners to offer them somewhere to jump in the moment of crisis. You were seldom doing the speaker a favor by pushing them into nihilism.
Eliezer Yudowsky might call this courtesy “leaving a line of retreat.” A Christian who thinks it is impossible to behave morally without faith in God cannot possibly deconvert. Before trying to persuade them the atheist side is right, you need to demonstrate the the hypothetical world in which the atheists are right is not unlivable. Yudkowsky got the name of this tactic from the advice of Sun Tzu in The Art of War:
When you surround the enemy
Always allow them an escape route.
They must see that there is
An alternative to death.
From the beginning of the play, Spinoza knows he’s smarter than almost everyone else on the stage. Out of a combination of arrogance and ebullience, he keeps going over their heads and leaves them gasping, trying to catch up. The cross-examination leads him to an epiphany that he finds satisfying and invigorating, but his interlocutors are left one step behind, still on the verge of nihilism.
Just like a chemistry teacher talks about electrons whizzing around nuclei in precise orbits until you’ve taken enough classes to wrap your head around the VSEPR model, philosophers might refrain from upsetting the sufficiently-not-terrible ideas of someone who hadn’t signed on to the philosophical project and honed their reasoning skills. The danger is that philosophy is a much less efficiently self-regulating field than chemistry.
Even if their art becomes arcane to most of us, chemists can hold each other to account, and the errors they haven’t caught yet aren’t likely to endanger the rest of us, since most of our day-to-day actions don’t depend on precise understandings of quantum theory. But philosophers sound like they’re having conversations on our level, so there’s more danger of confusion. On the other hand, if the philosophers retreat from the laypeople and lack a way to make their metaphysics pay rent, we’ll end up with more papers of this sort and the chaos that followed.
