  1. IDEA 1 OF 8

    Russell explains his disbelief

    In this lecture, Russell explains why he does not consider himself a Christian.

    He defines a Christian as someone who believes in God and immortality and in Christ as at least the best of men, and he examines the reasons usually given for these beliefs.

  2. IDEA 2 OF 8

    The first cause argument fails

    Russell argues that the idea that everything must have a cause leads to the question of what caused God.

    If God needs no cause, he says, neither might the world.

  3. IDEA 3 OF 8

    Natural laws need no lawgiver

    Russell argues that natural laws describe how things behave rather than commands given by someone.

    So the existence of laws of nature does not prove a divine lawgiver. Laws describe patterns.

  4. IDEA 4 OF 8

    Design arguments are weak

    Russell questions the argument that the world shows signs of design.

    He points to suffering and imperfection, suggesting that an all-powerful designer could have done better. The world seems far from perfect.

  5. IDEA 5 OF 8

    Morality does not require God

    Russell argues that the idea of right and wrong does not depend on God.

    If God's commands are good because God is good, goodness must exist independently of God. The argument cuts both ways.

  6. IDEA 6 OF 8

    Christ's teachings are questioned

    Russell admires some of Christ's teachings but criticises others, such as belief in eternal punishment.

    He argues that Christ was not the wisest or kindest of men in every respect.

  7. IDEA 7 OF 8

    Fear underlies religion

    Russell argues that religion is largely based on fear: fear of the unknown, of death and of defeat.

    He believes science can help people overcome these fears. Fear, he says, breeds cruelty.

  8. IDEA 8 OF 8

    Courage and reason are needed

    Russell concludes that people should face the world with courage and intelligence rather than depending on comforting beliefs.

    He hopes for a world guided by knowledge and kindness. Knowledge should guide life.
