The other bit about Pablo and the other Painting Masters of that time (Manet, Monet, Degas, Renoir, Cezanne, etc.) was that photography was becoming popular and painting realistic human and still life and landscape works was quickly being upstaged by the new technology. So they realized they had to do something unique or become "old hat". So then you get Impressionism, Cubism etc.
I disagree. Picasso was a sexist user of women, but I think sometimes the distortion in his works showed his love of all the erotic parts of a woman, shown all at once, rather than his dislike of women.
The analysis of his pre-cubist Demoiselles d’Avignon, shown a few posts above, would take too long here. Again, it is rather sexist, but it is also strongly painted and revolutionary in terms of space.
Remember, the camera had been invented in 1839, and from that point on, artists were free to be much more subjective in terms of style because they did not have to be tied to realism any more. Abstraction is a fascinating study, but not one to be done quickly.
