We live in an age that rev­els in reveal­ing secrets — from using genet­ic-test­ing kits that may uncov­er half sib­lings, to unbur­den­ing our­selves to ther­a­pists, to being bold­ly hon­est on the inter­net. But is there val­ue some­times in keep­ing secrets? This is one of the cen­tral themes I explore in Hill of Secrets, a WWII nov­el set in Los Alam­os, New Mex­i­co, where the world’s first atom­ic bomb was built — in secret. The nov­el fol­lows five main char­ac­ters liv­ing on the site who have their own per­son­al secrets, even as they are wrapped up in this larg­er one. Some of these secrets cor­rode their rela­tion­ships, while oth­ers pro­tect them.

I raise the issue in my nov­el in part because of my own mixed feel­ings about secrets. So much good can come from hon­esty. And yet, I won­der if the pen­chant for telling-it-all some­times car­ries a price that is too high, and caus­es unnec­es­sary pain. With my nov­el, I want to prompt read­ers to weigh the val­ue of secre­cy and of disclosure.

My ambiva­lence about secrets led me to con­sid­er how Jew­ish the­ol­o­gy and tra­di­tion view secre­cy. It turns out that on the whole, Judaism looks favor­ably on it.

Let’s start with the name of the Almighty, YHVH. The pro­nun­ci­a­tion of YHVH itself is con­sid­ered a close­ly guard­ed secret, to be revealed only to a select few. And the Almighty keeps secrets from us, which is why there is so much that we do not under­stand. At the same time, the Almighty knows all our secrets, so he is our con­fi­dante, keep­ing our secrets from oth­ers. In a sim­i­lar vein, the Kab­bal­ah is a secre­tive tra­di­tion, only to be shared grad­u­al­ly with the ini­ti­at­ed, enhanc­ing its pow­er and author­i­ty. The Essenes, who inhab­it­ed the area around the Dead Sea in Roman times, trea­sured secre­cy, their prac­tices large­ly unknown to oth­er Jews.

In Prophets, the telling of secrets is equat­ed with gos­sip­ing or bad-mouthing (לָשׁוֹן הָרַע or lashon hara) and is there­fore unde­sir­able. One who goes about as a gos­sip reveals a secret, but the faith­ful in spir­it con­ceals a mat­ter” (Proverbs 11:13). Rashi inter­pret­ed cer­tain texts to indi­cate that if a schol­ar is asked inti­mate ques­tions regard­ing his mar­i­tal life, he need not answer truthfully.

Fur­ther­more, in the Com­men­taries, even if the rev­e­la­tion of a secret is not gos­sip, one vio­lates a person’s trust by reveal­ing a secret. Rabbeinu Yon­ah writes in Sha’arei Teshu­vah (3:225), One is oblig­at­ed to con­ceal a secret told him by his fel­low even if there is no issue of tale mon­ger­ing in reveal­ing the secret.”

Only when secre­cy caus­es harm to anoth­er does Judaism allow divulging a secret — but only after try­ing to con­vince the wrong­do­er to con­fess on his/​her own.

In Jew­ish his­to­ry as well as tra­di­tion, keep­ing secrets has often been life­sav­ing. Con­sid­er baby Moses, Queen Esther, the Con­ver­sos dur­ing the Inqui­si­tion, or Jews hid­ing from the Nazis, to name just a few exam­ples. There is pow­er in secrets. They grant agency to per­se­cut­ed Jews (and oth­er per­se­cut­ed minorities).

Secrets can also help pre­serve a com­mu­ni­ty — for bet­ter or worse. Like in oth­er reli­gious insti­tu­tions, sex­u­al abuse and preda­to­ry behav­ior have some­times been hid­den by the Jew­ish com­mu­ni­ty. In her book, Shan­da: A Mem­oir of Shame and Secre­cy, Let­ty Cot­ton Pogre­bin explores the great fear of shame in Jew­ish fam­i­lies and the reluc­tance of the Jew­ish com­mu­ni­ty to air its dirty laun­dry in public.

Else­where in Jew­ish lit­er­a­ture, keep­ing secrets is some­times for the best. To cite a few exam­ples: In Philip Roth’s The Ghost­writer, Anne Frank lives in hid­ing in Ver­mont because she does not want to destroy the impact her diary has had on the world. In James McBride’s The Heav­en & Earth Gro­cery Store, good secrets abound, includ­ing help­ing to save a child from being insti­tu­tion­al­ized and with­hold­ing infor­ma­tion about how the com­mu­ni­ty obtains water for its syn­a­gogue. In Rachel Kadish’s The Weight of Ink, a scribe must hide that she is a woman in order to engage in her intel­lec­tu­al pur­suits. In Ayelet Gundar-Goshen’s nov­el Wak­ing Lions, an Eritre­an woman keeps an Israeli doctor’s secret to black­mail him into pro­vid­ing oth­er refugees with med­ical care.

In my own book, Hill of Secrets, there is a mix of secrets — some destruc­tive, some pos­i­tive. At one point, one of my hero­ines, Chris­tine, mus­es that she grew up believ­ing that telling the truth was always good, how­ev­er hard some­times. But there was need­less pain in truth. Some­times decep­tion was kind­ness … ” Anoth­er char­ac­ter, Sarah, finds relief in unbur­den­ing her secret.

In the end, per­haps it is best to be dis­cern­ing about secrets, sep­a­rat­ing the self-serv­ing ones from the self-pre­serv­ing ones, and speak­ing out to pre­vent harm, but hold­ing onto secrets when­ev­er divulging them in the name of truth will cause noth­ing but pain.
