Franklin was raised in a Puritan household, but he later rejected some of the more rigid aspects of his upbringing. However, values of hard work and diligence remained with him throughout his life.

Franklin embraced Deism, a philosophical belief that emphasizes reason and natural law over traditional religious dogma. Deists believe in a creator God but reject the idea of divine intervention or miracles.

Franklin focused on practical morality and ethical conduct, believing that individuals should strive to be virtuous and contribute to the common good, regardless of their religious beliefs. He developed a system of thirteen virtues that he sought to cultivate in his own life.

Franklin devised a system of thirteen virtues: Temperance, Silence, Order, Resolution, Frugality, Industry, Sincerity, Justice, Moderation, Cleanliness, Tranquility, Chastity, and Humility. He kept a journal and tracked his progress in cultivating each virtue, demonstrating his commitment to self-improvement and ethical living.
