Atheism and Agnosticism (Leaving Cert Religious Education): Revision Notes
Atheism and agnosticism
These are two important non-religious approaches to understanding life's big questions, particularly about the existence of God. Both positions reject traditional religious answers but in different ways.
Atheism
Definition: Atheism is the rejection or denial of God's existence. Atheists do not believe in any divine being or supernatural creator.
Interestingly, the very definition of atheism (as a denial) suggests that the concept of God exists for atheists to reject - they are responding to religious claims rather than ignoring them entirely.
Types of atheism
There are two main forms that atheist thinking can take:
Theoretical atheism bases its rejection of God on scientific evidence and rational thinking. Theoretical atheists point to discoveries like evolution as evidence against religious creation stories. They argue that biological life developed over billions of years through natural processes, not through divine creation in a matter of days. This approach uses scientific method and evidence to challenge religious explanations of existence.
Practical atheism takes a different approach entirely. Practical atheists consider questions about God's existence to be irrelevant and pointless. Rather than actively arguing against God's existence, they simply dismiss the entire debate as having no bearing on their lives or decision-making.
Agnosticism
Definition: Agnosticism holds that if something cannot be explained or proven through reason and science, then it cannot truly be known and most likely does not exist. Agnostics apply this thinking particularly to questions about God.
The agnostic position
Agnostics maintain a position of uncertainty about God's existence. They argue that there is insufficient evidence either to prove or disprove God's existence. This leads them to take a middle ground approach.
Agnostics say they would be willing to believe in God if convincing evidence emerged to support God's existence. Similarly, they would move towards atheism if strong evidence emerged against God's existence. Since neither type of evidence exists in their view, they choose not to commit to either position.
How agnostics approach life
Rather than making definitive statements about God, agnostics focus on evidence-based living. They centre their lives around humanist principles and scientific discoveries that can be proven and tested. For example, they might use medicine because its effectiveness has been demonstrated through scientific research.
This approach allows agnostics to make practical decisions based on available evidence whilst remaining open to new information that might change their perspective on ultimate questions.
Key differences
The main difference lies in their certainty levels. Atheists definitively reject God's existence (though for different reasons), while agnostics maintain that we simply cannot know for certain. Atheists have made their decision, whilst agnostics deliberately avoid making one.
Key Points to Remember:
- Atheism means rejecting or denying God's existence completely
- Theoretical atheism uses scientific evidence like evolution to argue against God
- Practical atheism considers God-questions irrelevant to daily life
- Agnosticism claims we cannot know if God exists and chooses to remain undecided
- Agnostics base life decisions on evidence and scientific proof rather than religious belief
