The Fountainhead
There are three speeches from "The Fountainhead": one by the antagonist Ellsworth Toohey, one which is actually more of a conversation between the sympathetic character Gail Wynand and the hero Howard Roark, and one which is Howard Roark's triumphant courtroom speech. The last is a statement of Rand's philosophy as it existed at the time of writing "The Fountainhead", and is a testimony to the human spirit expressed in individual invention and achievement.
