The basis of all reasoning is the mind's awareness of itself. What we think, the external objects we perceive, are all like actors that come on and off stage. But our consciousness, the stage itself, is always present to us.
What genuine painters do is to reveal the underlying psychological and spiritual conditions of their relationship to their world; thus in the works of a great painter we have a reflection of the emotional and spiritual condition of human beings in that period of history. If you wish to understand the psychological and spiritual temper of any historical period, you can do no better than to look long and searchingly at its art. For in the art the underlying spiritual meaning of the period is expressed directly in symbols. This is not because artists are didactic or set out to teach or to make propaganda; to the extend that they do, their power of expression is broken; their direct relations to the inarticulate, or, if you will, 'unconscious' levels of the culture is destroyed. They have the power to reveal the underlying meaning of any period precisely because the essence of art is the powerful and alive encounter between the artist and his or her world." (pg 52)
