    The first and most important rule of legitimate or popular
    government, that is to say, of government whose object is the
    good of the people, is therefore, as I have observed, to follow
    in everything the general will. But to follow this will it is
5   necessary to know it, and above all to distinguish it from the
    particular will, beginning with one's self: this distinction is
    always very difficult to make, and only the most sublime virtue
    can afford sufficient illumination for it. As, in order to will,
    it is necessary to be free, a difficulty no less great than the
10  former arises — that of preserving at once the public liberty
    and the authority of government. Look into the motives which have
    induced men, once united by their common needs in a general
    society, to unite themselves still more intimately by means of
    civil societies: you will find no other motive than that of
15  assuring the property, life and liberty of each member by the
    protection of all. But can men be forced to defend the liberty
    of any one among them, without trespassing on that of others?
    And how can they provide for the public needs, without alienating
    the individual property of those who are forced to contribute to
20  them? With whatever sophistry all this may be covered over, it is
    certain that if any constraint can be laid on my will, I am no
    longer free, and that I am no longer master of my own property,
    if any one else can lay a hand on it. This difficulty, which would
    have seemed insurmountable, has been removed, like the first, by
25  the most sublime of all human institutions, or rather by a divine
    inspiration, which teaches mankind to imitate here below the
    unchangeable decrees of the Deity. By what inconceivable art has a
    means been found of making men free by making them subject; of
    using in the service of the State the properties, the persons and
30  even the lives of all its members, without constraining and without
    consulting them; of confining their will by their own admission; of
    overcoming their refusal by that consent, and forcing them to punish
    themselves, when they act against their own will? How can it be that
    all should obey, yet nobody take upon him to command, and that all
35  should serve, and yet have no masters, but be the more free, as, in
    apparent subjection, each loses no part of his liberty but what might
    be hurtful to that of another? These wonders are the work of law. It
    is to law alone that men owe justice and liberty. It is this salutary
    organ of the will of all which establishes, in civil right, the
40  natural equality between men. It is this celestial voice which
    dictates to each citizen the precepts of public reason, and teaches
    him to act according to the rules of his own judgment, and not to
    behave inconsistently with himself. It is with this voice alone that
    political rulers should speak when they command; for no sooner does
45  one man, setting aside the law, claim to subject another to his
    private will, than he departs from the state of civil society, and
    confronts him face to face in the pure state of nature, in which
    obedience is prescribed solely by necessity.

    The tale of Piltdown Man, the most infamous forgery in the
    contentious detective story of the origins of mankind, began in
    1912. On December 18 that year Charles Dawson, a well-known
    amateur British archaeologist, and Arthur Smith Woodward, of
5   the British Museum of Natural History, announced the discovery
    of some amazing human fossils. The remains comprised nine pieces
    of skull, a broken jaw with two teeth in place, a few stone tools,
    and some animal bones, all of which had been discovered on a farm
    near Piltdown Common in Sussex.

10  When pieced together the skull looked distinctly human. Although
    Piltdown Man, as the hominid became known, had unusually thick
    bones, the brain case was large and rounded. There was no sign
    of prominent brow ridges or other apelike features. However, the
    shape of the jaw bone resembled that of an ape. The only human
15  characteristic of this jaw was the wear on the two molars, which
    were ground down flat, as is frequently true of hominids who eat
    tough or abrasive foods, such as seeds. In other words the
    creature had the jaw of an ape and the skull of Homo sapiens.

    The primitive stone tools found with these remains suggested a
20  remote age for Piltdown Man, perhaps the Early Pleistocene or
    even the Late Pliocene. (In 1912 experts thought the Pliocene
    lasted from 1 million to 600 000 years ago. Scientists now date
    it to between 5 million and 1.7 million years ago.) This date
    was also supported by some animal bones found with Piltdown Man.

25  To most scientists of the time, Piltdown Man fulfilled a
    prediction made by the pioneering evolutionist Charles Darwin,
    who had believed that humans and the apes could be connected
    genetically through a still undiscovered creature. Most
    significantly, it was half-human in precisely the feature
30  that was then accepted as the most important difference
    between humans and the apes - the brain. At this time there
    was little fossil evidence to contradict the idea that the
    brain was among the first of the human features to evolve.

    As time went on, however, Homo erectus fossils were found in
35  Java and China, while in South Africa the australopithecines
    were being discovered. All these fossils had human-like jaws
    and teeth and relatively small brains in contrast to Piltdown
    Man's large cranium and apelike jaw. The large brain simply
    did not fit with the rest of the fossil evidence. By 1948
40  scientists knew that bones buried in the earth gradually
    absorb fluorine. The older a bone, the more fluorine it
    contains. When the Piltdown materials were tested for fluorine,
    the skull and jaw fragments turned out to be much younger
    than the Early Pleistocene animal bones with which the skull
45  had been found.

    Scientists were now very suspicious. In 1953 all the Piltdown
    material was tested for its authenticity. Not only was the
    recent age of the jaw and skull confirmed, but the jaw proved
    to be that of a modern orangutan, with the teeth filed down
50  in a quite obvious manner to imitate wear on human teeth.
    But the forger had not stopped there. A bone tool found
    with the remains had been made in recent times with a steel
    knife, which leaves different marks than does a stone flake
    or axe. The tools, as well as the animal bones, had been
55  taken from different archaeological sites.

    Once the forgery was exposed by modem scientific analysis
    the mystery was no longer where Piltdown Man came in human
    evolution but who was responsible for the hoax, and why?
    Although Dawson, the discoverer of most of the Piltdown
60  material, is frequently singled out as the person responsible
    for this practical joke, there is no definite proof and the
    question is far from settled.
