The word imagination shimmers in the mind along with 'inspiration' on a higher level than invention, construction or observation. In the Renaissance mind and earlier the true artists were the poets. Painters and sculptors suffered under the lesser designation as artisans/craftsmen. Unrecognised as artists because they were simple copyists, therefore without imagination. Vasari and his artist subjects worked hard to change this by equating their efforts with the imagination of the poet. Thanks to their efforts the visual arts now seem to top the charts as far as prices paid for our products are concerned. But there is a down side.
In the arts the word has come to mean working without reference to nature. So the expectation of imagination from the visual arts has inadvertently come to mean fantasy: to out weigh observation. Whereas what we have actually admired in the past is the vivid observation of nature in which imagination enters as much and as little as in daily life. The patches of light that come to our retina have to be interpreted by the brain. They are recognised usually in spite of inadequate data.
Every act of recognition requires memories and imagination. When I look at the chair beside my bed I see patches of dark brown and lighter brown light. The colour relationships remind me of corduroy and my memory of casting aside my trousers allows me to recognise the patches of light as my trousers but there is no evidence in the shapes I see that these are indeed trousers. It is the memory of light on corduroy that has given the clue to my deduction. Every act of recognition could be described as a discovery because we need imagination for the simplest acts that allow us to find our way in the world. Imagination is not rare it is an every day necessity.
When Copernicus discovered that the earth was circling the sun he was using his imagination to see the orbits from outer space. That discovery has shaken the world so badly that had he advertised it he would probably have been burnt at the stake. There is a qualitative and a quantitative difference between my finding of my trousers and Copernicus' vision based on data that was thousands of years old. His was the greatest leap of the imagination made by Man. It has reduced our status from the centre of the universe to a tiny speck in a probable multiverse. The imagination has grown in status based on Copernicus and his like but it is sensible to regard it also as normal and everyday. We need to distinguish between the low flights of fancy and the high flights of imagination.
The significance of a discovery needs to be the measure of its importance. We need to take some of the unreasonable shine from the word. Imagination can be vastly important or everyday insignificant. I fear that art historians have been over impressed by Vasari's arguments and have illogically reasoned that as Rembrandt is undoubtedly exceptional he must therefore have worked from imagination. Alas. this is hopelessly wide of the mark. Yes Rembrandt possessed a wonderful imaginative empathy with his subjects but he observed them in reality. The scholars have imposed on a master of immeasurable importance, one who consistently claimed to work from observation “anything else was worthless in his eyes” - a method of work that does not fit at all. To make him fit his new work description they have had to discard more than half his genuine works. When Rembrandt is obliged to work by construction, with flying angels for instance, he makes sure that we do not take him seriously. (Link to flying angels)
It is indeed surprising that so many scholars have subscribed to the absurd idea of his imaginative construction for so long in the face of so much contrary evidence, and while doing immeasurable harm. My article on Rembrandt's use of mirrors (Burlington Feb.1977) should have dispelled any remaining doubts about the unanimous testimony of Rembrandt's contemporaries in this respect. Changing entrenched beliefs requires much patience – as Max Plank observed “science advances funeral by funeral”. The damage to Rembrandt and therefore to art continues unabated. At Harvard the only time we came near to debating the issue – I would claim to have won hands down but clearly the scholars took a different view because they have brushed aside my evidence as if it did not exist. There is no evidence for their view other than the fact that many scholars have accepted it unquestioningly for nearly one hundred years!
