Judea Pearl is Chancellor’s Professor of Computer Science and Statistics at UCLA and president of the Daniel Pearl Foundation.

Dear Professor West,

This is a humble request sent to you from a rank-and-file Jewish professor at the University of California, Los Angeles, where you are scheduled to deliver a keynote address in honor of Rabbi Abraham Joshua Heschel, titled “Moral Grandeur and Spiritual Audacity.” My request may sound odd, perhaps even audacious, but it needs to be said as we are preparing to commemorate the life and legacy of Rabbi Heschel, his moral grandeur and his spiritual audacity.

I will be as blunt and straightforward as possible: You should excuse yourself from delivering this lecture. My reasons are also blunt and straightforward: No matter how eloquent your speech and how crafty your words, the audience you will face at UCLA will not be able to take them too seriously in light of your recent decision to become a leading propagandist for the Boycott, Divestment and Sanctions (BDS) movement. You have to forgive us for being pedantic in these matters, and perhaps not as flexible and nuanced as one might hope, but our history has taught us the importance of devising crisp and visible litmus tests to distinguish friends from foes. It so happened, and you know it as well as we do, that the term BDS has become our most reliable litmus test. In other words, we have come to equate promoters of BDS ideology with those who seek the destruction of Israel, hence the demise of the Jewish people.

Thus, as much as we might try to separate the words you would be saying in honor of Rabbi Heschel from those you uttered in a Feb. 25interview with David Palumbo-Liu at Stanford (published in Salon), in which you took great pride in promoting cultural and academic boycotts of Israel, our minds will resist the separation. Our minds will be warning us, again and again, that the person speaking before us wants our destruction.

The human mind is a funny machine, Professor West, unlike for politicians and entertainers, our mind seeks consistency and coherence in everything that we see and hear. This stubborn mind will therefore not allow us to forget that in your Aug. 12, 2014, interviewwith Sean Hannity, you could not find even one historical link between the Jewish people and the land of Israel. None! Nada! Blank! Not one word of empathy for a multiethnic society of immigrants who’ve fought 67 years of besiegement and hostility. None! Nada!Blank! Thus, Professor West, you will have to forgive those stubborn minds if they remind your audience that the keynote speaker at the Heschel memorial conference does not represent the ecumenical legacy of Rabbi Heschel (1907-72), but the moral deformity of BDS.

I believe your UCLA hosts, and certainly your UCLA audience, will accept your apologies if you decide to cancel your engagement. They would understand
