What happens

Paine contrasts the Christian system with the evidence of nature and the universe, recounting his early doubts about Christian doctrine, his education in science, and his argument for a plurality of worlds. He criticizes Christian mythology, especially the story of redemption, and advocates for Deism as a pure and simple faith based on contemplation of the Creator's works.

Themes in this chapter

  • Deism and Natural Theology

    Paine contrasts the pure and simple profession of Deism with Christian mythology, emphasizing contemplation of the Deity in his works.

  • Critique of Organized Religion

    Paine criticizes the Christian story of redemption as shocking to a child and argues that any system of religion that shocks a child cannot be true.

  • Science vs. Superstition

    Paine uses his knowledge of globes, orrery, and natural philosophy to confront the Christian system with the evidence of the universe.

  • Reason vs. Revelation

    Paine relies on reason and observation of nature to challenge revealed Christian doctrines.

Characters to notice

  • Thomas Paine

    Author and narrator; recounts his Quaker upbringing, early doubts about Christianity, and his turn to science and Deism.

  • Jesus Christ

    Referenced in the context of the Christian story of redemption by the death of the Son of God.

Key passages

  • I either doubted the truth of the Christian system, or thought it to be a strange affair; I scarcely knew which it was: but I well remember, when about seven or eight years of age, hearing a sermon read by a relation of mine, who was a great devotee of the church, upon the subject of what is called 'Redemption by the death of the Son of God.'

    Paine recalls that from a young age he doubted Christianity, especially after hearing a sermon on redemption at age seven or eight.

    Paine's early skepticism about Christian doctrine.

  • The true deist has but one Deity; and his religion consists in contemplating the power, wisdom, and benignity of the Deity in his works, and in endeavouring to imitate him in everything moral, scientifical, and mechanical.

    A true deist worships one God by studying nature and striving to emulate God's moral and scientific attributes.

    Paine's definition of Deism.

  • The two beliefs can not be held together in the same mind; and he who thinks that he believes both, has thought but little of either.

    Belief in a plurality of worlds is incompatible with the Christian system; anyone claiming to hold both has not deeply considered either.

    Paine argues that Christianity and a scientific view of the universe are mutually exclusive.
