legitimacy of custom, and the essential principles of law. Delving daily
into the foundations of society as it was then constituted, they studied
its structure intently and criticized its overall plan. To be sure, not all of
them pondered these great problems in a thorough or profound manner.
Indeed, most touched on them only supercially, almost playfully. But all
considered them. Abstract and literary politics of this sort was to be found
in all the works of the period, though not to the same degree. None was
entirely exempt, from the weightiest treatise to the most frivolous song.
The political systems of these writers varied so widely that it would be
impossible to combine them all into a single theory of government.
Nevertheless, if we ignore details and look for fundamental ideas, we
soon nd that the authors of these various systems agreed on at least
one very general notion, which each of them seems to have conceived
on his own – a general notion that seems to have preexisted, and to be
the common source of, all the other, more specic ideas. However much
the authors of the time eventually diverged from one another, all started
from the same place: all believed that it was proper to replace the complex
traditional customs that governed the society in which they lived with
certain simple, elementary rules, which could be deduced from reason
and natural law.
Careful study reveals that what one might call the political philoso-
phy of the eighteenth century consists, strictly speaking, in this single
notion.
Such a thought was not new: for three thousand years it had peri-
odically gripped the human imagination, though never for long. How
was it that it now seized the minds of so many writers? Why, instead
of remaining conned within a few philosophical heads, as had always
been the case before, did it lter down to the masses and take on the
substance and warmth of a political passion, to the point where we nd
general and abstract theories about the nature of society becoming the
subject of daily conversation among those with nothing else to occupy
them and inaming the imaginations of even women and peasants?
How did men of letters without rank, honor, wealth, responsibility,
or power become, in fact, the leading politicians of the age – nay, the
only politicians, since, while others engaged in government, they alone
wielded authority? I would like to explain this briey and show what
extraordinarily powerful inuence these facts, which seem to belong to
the history of our literature, had on the Revolution and continued to
have down to the present time.
