"The great act of faith is when a man decides he is not God"

This quote by Oliver Wendell Holmes, Jr. talks to the idea of humbleness and the acknowledgment of one's own constraints. It recommends that a fantastic act of faith is when an individual has the ability to acknowledge that they are not all-knowing or all-powerful, and that there are things outside of their control. This is a difficult awareness for lots of people, as it requires a particular level of self-awareness and acceptance of one's own death. It is a reminder that no matter how much understanding or power a person may have, they are still human and subject to the very same laws of nature as everybody else. By acknowledging this, a person can have faith in something higher than themselves and can discover peace in the knowledge that they are not alone in deep space.
