Take for example the many paintings of St. Michael's Mount that any visitor to Penzance or anywhere else in West Cornwall would be confronted with in the many art galleries found in those parts. They are almost all looking from the beach opposite (usually Marazion) or from a little higher up or even from the point of view of the sea. Again it might seem obvious to look from a good vantage point.
But to me this is not very interesting because it is not the view that someone living and working in the area normally sees. Not unless they have a lot of money and an incredible view and most people do not. It is also usually a timeless view as it has no historical context. It is a painting that could have been painted at any point in the last hundred years. To me, a painting without relation to the times or the people living and working in the area is pointless, it must be contextualised.
To me, a landscape painting needs to tell us something about the relationship between nature and humanity. It is not enough to simply present nature as something timeless and unchanging and that stands on its own. To me that suggests a desire to escape human society to an imaginary natural paradise. I don't want to escape the human world, I want to change it.
