Quick Summary

Natural theology is the study of God and religious truths through reason and the observation of nature, rather than through divine revelation. This philosophical approach seeks to establish religious beliefs, such as the existence of God, by examining the natural world and inferring design or purpose.12

Key aspects include:
* Methodology: Relies on rational arguments and empirical evidence from nature.12
* Focus: Traditionally centers on proving God's existence and the soul's immortality.2
* Contrast: Differs from revealed theology, which is based on divine communication.3

The argument from design, a prominent aspect of natural theology, suggests that the complexity and order observed in nature imply an intelligent designer. However, this argument has faced criticism, with alternative explanations like natural selection proposed.2
