And now the miracle is that this happened!, that actually, in all these realms, the prophecy, under the principle of harmony, was really verified. The greatest upward development of economy, a very strong type of religion, where 217 different denominations don’t mean anything: if you come as an observer from the outside and see the Protestant world, it is a conformity in spite of all this. And if you look at democracy, in spite of the disruptive tendencies which again today are very much visible in America, democracy has worked and is still working. And so in all other realms. This means this third principle is the ultimate principle on which the belief in progress, in spite of lack of authority, is rooted.
Now I come to a few other representatives of the Enlightment – John Locke. I want only to use one concept we must keep in mind, the concept: of tolerance, which is also a product of the development towards the Enlightment. Tolerance has many reasons. One of the main historical reasons was that intolerance would have finally destroyed all Europe. The religious wars almost destroyed it, and it could be saved only by a tolerant state which is indifferent toward all the different fighting confessions. But this is only one point.
When John Locke wrote his 1etters on tolerance, he was very aware that tolerance never can be an absolute principle. So he limited it in a very interesting way. He was the leader of the Enlightenment; he, the type of man who influenced 18th century England more than anybody else – it is, very rare that a philosopher had such influence as John Locke had – he nevertheless said there are two groups which cannot be admitted, against which in the name of tolerance we must be intolerant.
