This conflict of sanctions is of great importance in considering whether these sanctions, as at present capable of being foreseen, are sufficient in all cases to determine a rational egoist to the performance of social duty: for the more stress we lay on either the legal or the social sanctions of moral conduct, the greater difficulty we shall have in proving the coincidence of duty and self-interest in the exceptional cases in which we find these sanctions arrayed against what we conceive to be duty. But even if we put these cases out of sight, it still seems clear that the external sanctions of morality alone are not always sufficient to render immoral conduct also imprudent. We must indeed admit that in an even tolerably well-ordered society--_i.e._ in an ordinary civilised community in its normal condition--all serious open violation of law is contrary to prudence, unless it is an incident in a successful process of violent revolution: and further, that violent revolutions would very rarely--perhaps never--be made by a combination of persons, all perfectly under the control of enlightened self-love; on account of the general and widespread destruction of security and of other means of happiness which such disturbances inevitably involve. Still, so long as actual human beings are not all rational egoists, such times of disorder will be liable to occur: and we cannot say that _under existing circumstances_ it is a clear universal precept of Rational Self-love that a man should “seek peace and ensue it”; since the disturbance of political order may offer to a cool and skilful person, who has the art of fishing in troubled waters, opportunities of gaining wealth, fame, and power, far beyond what he could hope for in peaceful times. In short, though we may admit that a society composed entirely of rational egoists would, when once organised, tend to remain in a stable and orderly condition, it does not follow that any individual rational egoist will always be on the side of order in any existing community.[128] But at any rate, in the most orderly societies with which we are acquainted, the administration of law and justice is never in so perfect a state as to render _secret_ crimes always acts of folly, on the score of the legal penalties attached to them. For however much these may outweigh the advantages of crime, cases must inevitably occur in which the risk of discovery is so small, that on a sober calculation the almost certain gain will more than compensate for the slight chance of the penalty. And finally, in no community is the law actually in so perfect a state that there are not certain kinds of flagrantly anti-social conduct which slip through its meshes and escape legal penalties altogether, or incur only such legal penalties as are outweighed by the profit of law-breaking.
