The article discusses the transcendental function of hope in thought and inquiry based on the theories of philosophers Charles Peirce, Christopher Hookway and Sami Pihlström. Peirce refers to genuine altruism as a distinctly logical attitude necessary for the progress of inquiry. Hookway defends Peirce's views of progress in inquiry in his book "Truth, Rationality and Pragmatism." Pihlström argued that transcendental arguments are meant to answer the skeptics.
