Letter to Lambertus Grunnius (August 1516), publised in Life and Letters of Erasmus : Lectures delivered at Oxford 1893-4 (1894) http://books.google.com/books?id=ussXAAAAMAAJ&pg=PA180&lpg=PA180&dq=%22is+no+discipline+and+which+are+worse+than+brothels%22&source=bl&ots=PnJjrkSLNB&sig=JPY0PhTf2YgYwJlf3uH2eTvCJeA&hl=en&ei=BGwXTNqTA5XANu6_pJ8L&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBIQ6AEwAA#v=onepage&q=%22is%20no%20discipline%20and%20which%20are%20worse%20than%20brothels%22&f=false edited by James Anthony Froude, p. 180
Context: There are monasteries where there is no discipline, and which are worse than brothels — ut prae his lupanaria sint et magis sobria et magis pudica. There are others where religion is nothing but ritual; and these are worse than the first, for the Spirit of God is not in them, and they are inflated with self-righteousness. There are those, again, where the brethren are so sick of the imposture that they keep it up only to deceive the vulgar. The houses are rare indeed where the rule is seriously observed, and even in these few, if you look to the bottom, you will find small sincerity. But there is craft, and plenty of it — craft enough to impose on mature men, not to say innocent boys; and this is called profession. Suppose a house where all is as it ought to be, you have no security that it will continue so. A good superior may be followed by a fool or a tyrant, or an infected brother may introduce a moral plague. True, in extreme cases a monk may change his house, or even may change his order, but leave is rarely given. There is always a suspicion of something wrong, and on the least complaint such a person is sent back.

Tuer un parent de qui l’on se plaint, c’est quelque chose; mais hériter de lui, c’est là un plaisir!

Other translation:
Abstract art is only painting. And what's so dramatic about that? There is no abstract art. One must always begin with something. Afterwards one can remove all semblance of reality.
Richard Friedenthal (1968, p. 256-7).
Longer version:
Abstract art is only painting. And what's so dramatic about that? There is no abstract art. One must always begin with something. Afterwards one can remove all semblance of reality; there is no longer any danger as the idea of the object has left an indelible imprint. It is the object which aroused the artist, stimulated his ideas and set of his emotions. These ideas and emotions will be imprisoned in his work for good.. .Whether he wants it or not, man is the instrument of nature; she imposes on him character and appearance. In my paintings of Dinard, as in my paintings of Purville, I have given expression to more or less the same vision.. .. You cannot go against nature. She is stronger than the strongest of men. We can permit ourselves some liberties, but in details only (Boisgeloup, winter 1934).

Context: Abstract art is only painting. What about drama?
There is no abstract art. You always start with something. Afterward you can remove all traces of reality.
