It is absurd to say that any amount of public danger can justify a system like this, we do not say on Christian principles, we do not say on the principles of a high morality, but even on principles of Machiavellian policy. It is true that great emergencies call for activity and vigilance; it is true that they justify severity which, in ordinary times, would deserve the name of cruelty. But indiscriminate severity can never, under any circumstances, be useful. It is plain that the whole efficacy of punishment depends on the care with which the guilty are distinguished. Punishment which strikes the guilty and the innocent promiscuously, operates merely like a pestilence or a great convulsion of nature, and has no more tendency to prevent offences than the cholera, or an earthquake like that of Lisbon, would have. The energy for which the Jacobin administration is praised was merely the energy of the Malay who maddens himself with opium, draws his knife, and runs amuck through the streets, slashing right and left at friends and foes. Such has never been the energy of truly great rulers; of Elizabeth, for example, of Oliver, or of Frederick. They were not, indeed, scrupulous. But, had they been less scrupulous than they were, the strength and amplitude of their minds would have preserved them from crimes such as those which the small men of the Committee of Public Safety took for daring strokes of policy. The great Queen who so long held her own against foreign and domestic enemies, against temporal and spiritual arms; the great Protector who governed with more than regal power, in despite both of royalists and republicans; the great King who, with a beaten army and an exhausted treasury, defended his little dominions to the last against the united efforts of Russia, Austria, and France; with what scorn would they have heard that it was impossible for them to strike a salutary terror into the disaffected without sending school-boys and school-girls to death by cart-loads and boat-loads!
