Americans like to take credit for creating modern democracy. The notion that we the people would be ruled by the people for the people lay dormant for centuries, until the founding fathers of this nation expressed such an idea as their national goal of statehood. We would all be free, but subject to majority rule. Two hundred years later, it is still safe to say that democracies based on majority rule are the most successful economically, politically and socially, by any standard.
As Jews, we should appreciate the fact that the concept of majority rule not only originated in Jewish tradition, but is in fact encrypted in halacha. Our Torah begins the very story of creation with G-d speaking to the angels stating naasa adam lets us make man, Berashis 1:26. Rashi is quick to point out the universal principle that one must take counsel from others before acting. The Talmud picks up this theme by demanding that Jewish courts be made of uneven number of judges so that there would never be a tie, but at all times a decision by a majority, Sanhedrin 3:a. The concept of majority rule is so cherished by Judaism that its absence leads to an automatic acquittal in capital cases. Thus, an amazing anomaly exists whereby a majority can convict a defendant of murder. Yet, a unanimous verdict of guilt is deemed inherently flawed, as cited in Sanhedrin 17a.
In addition to the judicial system, Jewish governments in ancient times respected the majority rule doctrine. Jewish kings were limited on many matters, including the most significant issue of going to war, requiring a majority ruling of the high court, Sanhedrin 20b.
