Ayn Rand's philosophical writings, particularly **Objectivism**, emphasized **individualism** and the moral superiority of **self-interest**. Her novels, such as **Atlas Shrugged** and **The Fountainhead**, promote the idea that the pursuit of personal happiness is the ultimate moral aim. Rand's philosophy critiques **collectivism** and advocates for **capitalism** as a means to achieve human potential. Her ideas have had a lasting impact on political and economic thought, influencing various movements centered around **freedom** and **libertarianism**. Rand's work continues to provoke debate on the role of the individual in society and the ethics of **self-realization**.
