All these differences are more important at critical periods, because government itself is more important. A formed public opinion, a respectable, able, and disciplined legislature, a well-chosen executive, a Parliament and an administration not thwarting each other, but cooperating with each other, are of greater consequence when great affairs are in progress than when small affairs are in progress⁠—when there is much to do than when there is little to do. But in addition to this, a Parliamentary or Cabinet Constitution possesses an additional and special advantage in very dangerous times. It has what we may call a reserve of power fit for and needed by extreme exigencies.
