What happens at Howard Roark’s trial in The Fountainhead?

In Ayn Rand’s novel The Fountainhead, the protagonist Howard Roark is brought to trial after he destroys a public housing project he designed. Roark took this action because government bureaucrats had altered his architectural plans against his explicit wishes, violating his creative integrity.1

During the trial, Roark delivers a significant speech in his own defense. In this address, he articulates his philosophy of objectivism, arguing for the moral superiority of individualism over collectivism and egoism over altruism. He maintains that an individual’s primary duty is to their own happiness and creative vision rather than living for the sake of others. Ultimately, the jury finds his arguments compelling and votes unanimously to acquit him of the crime.1
