Memorial Spinoza in The Hague

You're standing at the statue of Spinoza, on the Paviljoensgracht in The Hague. Don't look for a canal, though. It was filled in long ago. Now take a look at the man in the chair. He's lost in thought, wrapped in a long coat. His left hand rests on his knee, holding a small stack of papers. His right hand holds a pen and props up his head. A thinker, through and through.
