Arthur Schopenhauer
Schopenhauer believed that the primary characteristic, or essence of all things - including human beings - is not intelligence, rationality or spirit, but will. By "will" he means a wanting and craving like that which we know in ourselves as our "will." It is the source of immense amounts of suffering in the world. He also believed that a "better consciousness" could be attained by denying the fulfilment of our desires, taking time to think about who we really are and what we should do to avoid suffering - but also, in doing something few philosophers of his day spoke of: in making and looking at works of art, especially music, which he considered a way to escape from the world's pain and suffering.
