"Any institution is only a political structure. In physics and in morals, the laws are the same; you cannot build a large structure on a narrow foundation, nor a durable structure on a moving or transient base. In the political order, therefore, if one wants to build on a large scale and for the centuries, one must rely on an opinion, on a large and profound belief. For if this opinion does not dominate a majority of minds and if it is not deeply rooted, it will furnish only a narrow and transient base."
