Sci­ence, reli­gion, and the law have a com­mon basis: trust. Poly­the­is­tic reli­gions find their gods doing all the things we humans do — mis­lead­ing, deceiv­ing, cajol­ing, seduc­ing, com­pet­ing — only some­what bet­ter; monothe­is­tic reli­gions require con­sis­ten­cy the essence of trust. Trust traces the devel­op­ment of trust from Hebrew ori­gins and Chris­t­ian refine­ment through valu­able con­tri­bu­tions from Islam, and from there to sci­ence. Law both sacred and sec­u­lar respects the same log­i­cal rubric that is reflect­ed in monothe­ism. Trust exam­ines the Ten Com­mand­ments as a blue­print for a trust­wor­thy com­mu­ni­ty and con­cludes with sug­ges­tions for our cul­tur­al and genet­ic future.
