What is the most resilient parasite?
A bacteria? A virus?
An intestinal worm?
An idea.
Resilient. Highly contagious.
Once an idea has taken hold of the brain, it's almost impossible to eradicate.
An idea that is fully formed, fully understood, that sticks.

No matter what anybody tells you, words and ideas can change the world.

An idea is like a virus. Resilient. Highly contagious. And the smallest seed of an idea can grow. It can grow to define... or destroy you.

— I suppose they're gonna lock me up as well... as your accomplice.
— Accomplice? I'm gonna tell them the whole thing was your idea.

— Die! Die! Why won't you die? Why won't you die?
— Beneath this mask, there is more than flesh. Beneath this mask there is an idea, Mr. Creedy. And ideas are bulletproof.

No idea is simple when you need to plant it in somebody else's mind.

If you can steal an idea from someone's mind... why can't you plant one there instead?

The subject's mind can always trace the genesis of the idea. True inspiration's impossible to fake.

Something's wrong with the world. You don't know what, but it's there. Like a splinter in your mind driving you mad. It is this feeling that has brought you to me.

I have a million ideas. They all point to certain death.
