Let us begin then by laying facts aside, as they do not affect the question. The investigations we may enter into, in treating this subject, must not be considered as historical truths, but only as mere conditional and hypothetical reasonings, rather calculated to explain the nature of things, than to ascertain their actual origin; just like the hypotheses which our physicists daily form respecting the formation of the world. Religion commands us to believe that, God Himself having taken men out of a state of nature immediately after the creation, they are unequal only because it is His will they should be so: but it does not forbid us to form conjectures based solely on the nature of man, and the beings around him, concerning what might have become of the human race, if it had been left to itself. This then is the question asked me, and that which I propose to discuss in the following discourse. As my subject interests mankind in general, I shall endeavour to make use of a style adapted to all nations, or rather, forgetting time and place, to attend only to men to whom I am speaking. I shall suppose myself in the Lyceum of Athens, repeating the lessons of my masters, with Plato and Xenocrates for judges, and the whole human race for audience.
O man, of whatever country you are, and whatever your opinions may be, behold your history, such as I have thought to read it, not in books written by your fellow-creatures, who are liars, but in nature, which never lies. All that comes from her will be true; nor will you meet with anything false, unless I have involuntarily put in something of my own. The times of which I am going to speak are very remote: how much are you changed from what you once were! It is, so to speak, the life of your species which I am going to write, after the qualities which you have received, which your education and habits may have depraved, but cannot have entirely destroyed. There is, I feel, an age at which the individual man would wish to stop: you are about to inquire about the age at which you would have liked your whole species to stand still. Discontented with your present state, for reasons which threaten your unfortunate descendants with still greater discontent, you will perhaps wish it were in your power to go back; and this feeling should be a panegyric on your first ancestors, a criticism of your contemporaries, and a terror to the unfortunates who will come after you.

If they had any interest in changing it, then why haven't they done so?
