There is nothing more difficult to define than an aphorism.
Money is just an idea.
A lot of my books have started with an abstract premise.
The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
The roaring of the wind is my wife and the stars through the window pane are my children. The mighty abstract idea I have of beauty in all things stifles the more divided and minute domestic happiness.
Peace is a spirit, and not an intellectual abstraction.
Money is really just an idea.
'Look at Me' started with Rockford, Illinois and New York and the question of how much image culture was changing our inner lives. That's an abstract idea; you don't think that's going to be a rocking work of fiction, but it seemed to fuse in a way that was interesting.
A mathematical equation stands forever.
How badly I want that nameless thing! First there must be an idea, a feeling... Maybe it was an abstract idea that you've got to find a symbol for, or maybe it was a concrete form that you have to simplify or distort to meet your ends, but that starting point must pervade the whole.

I don't have a general archetypal platonic shadow, 'acting' concept about it.
Some speak of the public as if it were someone with whom they have had dinner at the Leipzig Fair in the Hotel de Saxe. Who is this public? The public is not a thing, but rather an idea, a postulate, like the Church.

Revenge is a particularly interesting concept, especially the notion of whether or not it exists outside of just an abstract idea.
Virtue, my pet, is an abstract idea, varying in its manifestations with the surroundings. Virtue in Provence, in Constantinople, in London, and in Paris bears very different fruit, but is none the less virtue.
A race is a work of art.
The sum total of all sums total is eternal.
I have said I have met Satan, and this is true. But it is not tangible. It no more has horns, hooves and a forked tail than God has a long white beard. Even the name, Satan, is just a name we have given to something basically nameless.
