I bought "Selected Writings" from the Shop of the Rene Magritte Museum in Brussels, Belgium. Prior to my visit, I didn't know that Magritte was so keen on writing. The book consists of well over 100 different works, ordered chronologically, which I find as a good decision, allowing one to sense the painter's development over time. The various texts shed light over different aspects of Magritte's life, motivations, beliefs, political views and opinions on different topics.
Personally, I find Magritte's thoughts on art very interesting. He has almost no interest in other painters, saying: "I don't expect any enlightenment from contemporary painters! I don't go to exhibitions. It's too boring!". Max Ernst and Giorgio de Chirico are two notable examples: "There are only two painters I think highly of: de Chirico and Max Ernst." and "Apart from de Chirico and Ernst, I do not know any contemporary painter who has even the remotest idea of a painting that is not influenced by intellectual habits that leave me indifferent".
Furthermore, he completely annihilates the idea of expressing ideas through painting: "I consider that words express ideas well enough, sometimes very beautiful ones, too often tedious ones - and painting doesn't have to add to them. Painting, as I see it, doesn't have to express ideas, even brilliant ones. If the painter has genius, he has a genius for images, not ideas". Rather, Magritte (being a Surrealist) is interested in: "the image that has appeared to me and that I consider has to be painted". Magritte goes on and discusses the mysterious, the person's interest in the unknown and the effect of an image on the observer.
In general, I agree with him, that it is very important what kind of feelings or thoughts an image provokes in us. It seems, that not everyone is understanding this and people get lost in "searching" for a meaning (in the classical sense), that the author tried to convey, be it realistically depicting a scene or telling a fable though a painting.
