Mathematician Blaise Pascal's collection of philosophical essays, Pensées, has various theological themes. One of the most prominent themes is the search for human existence's purpose. Pascal opines that the search for God is equivalent to the search for meaning in one's life. Therefore, our current human existence is part of our journey toward divinity.

Within this theme, Pascal states that the search for the divine will lead to immortality. He believes that our existence on Earth has limitations, such as human frailties and flaws. Humans—regardless of class and status—will all experience death, but there is a metaphysical plane beyond death.

Another theme in the text is Pascal's argument for the existence of God. God's existence itself is interlinked to our own existence. This symbiotic relationship between mortals and God is the essence of religion. However, Pascal also believes that rational thought will not conflict with religious faith. He recognizes that human behavior is rooted in thoughts, but he believes that the reasonable person will choose to believe in God, because it is the option that makes the most sense.
