This collection of essays was the last work Ayn Rand worked on before her death in 1982. In it, she summarizes and defends her philosophical views, which formed the basis of her best-selling books Atlas Shrugged and The Fountainhead. According to her ideas, reason is not just a distinctive, but a fundamental characteristic of man by which he survives. For Ayn Rand, philosophy is a force that shapes the consciousness and character of individuals and nations; A person’s choice is not whether to adhere to this or that philosophical concept or not, but which one to accept for himself. The writer criticizes Kant's ethical views, writes about the importance of language and explains what is necessary for the formation of a rational and conscious philosophy.
