This is a brilliant book by a man who was both ahead of his time and a captive of the age in which he lived. Just as Lessing shows us the limits of painting and poetry, their strengths and weaknesses as media of artistic expression, he also shows us the strengths and weaknesses of the Enlightenment -- rational, smart, analytical, discarding the prejudices of prior eras, but at the same time limited by an excessive faith in reason and unable to see its limits, sometimes harsh and lacking in humanism and heart, missing a sense of wonder, enchantment and spirituality. It would have been nice if he could have understood that art has value far beyond simple mimesis and portrayal of beauty, and if he could have had appreciation of cultures beyond Greco-Roman and Western European. But Lessing was no dope, and I think that if I could send him a time machine to transport him to the present day, he would quickly develop a broader perspective that would fit within his theories easily.
The most interesting part of this book for me was the discussion of how painting and sculpture, on the one hand, and poetry, on the other, have different capabilities and limitations that make each form of expression best at different types of artistic works. Because sculpture and painting give us a frozen moment they are stronger when they show a moment of anticipation to spur the imagination as to what comes next. They are also limited in space so they need to show people and things in proximity to one another. On the other hand, they provide a complete scene that can be apprehended all at once so there is an opportunity for the viewer to experience a sort of parallel processing that that makes the whole more than the sum of its parts. Poetry on the other hand has the characteristic of moving forward in serial form, so that its great strength is action over time and its greatest weakness in comparison to the visual arts is in providing descriptions of beauty, which it can only provide either in limited generality that leaves the reader to rely on his imagination or by finding ways to express beauty through action. Poetry also excels at presenting the unknown and invisible which in the visual arts can only be suggested by metaphor. And there is a lot more. This is good stuff that provides a lot of food for thought and that can be easily transposed into a more modern context where we now have movies, television and digital media, which each have their own strengths and limitations that shape the way that great artists use them in their creative process.
There were times when I disagreed with Lessing. For example he says that religious art is always inferior to secular art, because religious art is in service to the requirements of religion, but that misses the extra dimension that religion can also give to art, so more properly he should have talked about strengths and limits of religious vs secular art just as he did in comparing painting and poetry. And he should have considered how painting and sculpture are themselves different, how poetry is different from prose and how drama is different from all of them. But even if he was blind to some of these implications of his own thinking, he managed to get me going. I'll be thinking about his ideas for weeks, and they will come back to haunt me again the next time that I go to an art museum. It's hard to expect more than that from a book.
