The reasoning mind

"Man cannot survive except through his mind. He comes on earth unarmed. His brain is his only weapon. But the mind is an attribute of the individual, there is no such thing as a collective brain. The man who thinks must think and act on his own. The reasoning mind cannot work under any form of compulsion. It cannot not be subordinated to the needs, opinions, or wishes of others. It is not an object of sacrifice."

-- Howard Roark in the bestselling novel "The Fountainhead" by Ayn Rand
