Helvétius’s theory can be applied in two ways. One may interpret it to mean that the change in man’s social and political environment ought to be accomplished peacefully and gradually, through the reform of institutions and enlightenment. One can also conclude from it that this end is best attained by a violent destruction of the existing order.
Which approach—the evolutionary or revolutionary—prevails seems to be in large measure determined by a country’s political system and the opportunities it provides for intellectuals to participate in public life.
In societies which make it possible through democratic institutions and freedom of speech to influence policy, intellectuals are likely to follow the more moderate alternative. In eighteenth- and nineteenth-century England and the United States, intellectuals were deeply involved in political life. The men who shaped the American republic and those who led Victorian England along the path of reform were men of affairs with deep intellectual interests: of some of them it would be difficult to say whether they were philosophers engaged in statesmanship or statesmen whose true vocation was philosophy. Even the pragmatists among them kept their minds open to the ideas of the age. This interplay of ideas and politics lent political life in Anglo-Saxon countries their well-known spirit of compromise. Here the intellectuals had no need to withdraw and form an isolated caste. They acted on public opinion, which, through democratic institutions, sooner or later affected legislation.
In England and, through England, in the United States, the ideas of Helvétius gained popularity mainly from the writings of Jeremy Bentham and the utilitarians. It was to Helvétius that Bentham owed the ideas that morality and legislation were “one and the same science,” that man could attain virtue only through “good laws,” and that, consequently, legislation had a “pedagogic” function.15 On these foundations, Bentham constructed his theory of philosophical radicalism, which greatly affected the movement for parliamentary reform and liberal economics. The preoccupation of modern Anglo-Saxon countries with legislation as a device for human betterment is directly traceable to Bentham and, through him, to Helvétius. In the speculations of Bentham and the English liberals, there was no place for violence: the transformation of man and society was to be accomplished entirely by laws and enlightenment. But even under this reform-minded theory lay the tacit premise that man could and ought to be remade. This premise links liberalism and radicalism and helps explain why, for all their rejection of the violent methods employed by revolutionaries, when forced to choose between them and their conservative opponents, liberals can be counted on to throw their lot in with the revolutionaries. For what separates liberals from the extreme left is disagreement over the means employed, whereas they differ from the right in the fundamental perception of what man is and what society ought to be.
In countries which excluded intellectuals from participation in public life—of which old regime France and Russia were prime examples—intellectuals were prone to form castes committed to extreme ideologies. The fact was noted by Tocqueville:
In England, writers on the theory of government and those who actually governed cooperated with each other, the former setting forth their theories, the latter amending or circumscribing these in the light of practical experience. In France, however, precept and practice were kept quite distinct and remained in the hands of two quite distinct groups. One of these carried on the actual administration while the other set forth the abstract principles on which good government should, they said, be based; one took the routine measures appropriate to the needs of the moment, the other propounded general laws without a thought for their practical application; one group shaped the course of public affairs, the other that of public opinion. Thus, alongside the traditional and confused, not to say chaotic, social system of the day there was gradually built up in man’s minds an imaginary ideal society in which all was simple, uniform, coherent, equitable, and rational in the full sense of the term.16
