Religion and Non-Religion
Core concepts
You must be able to define non-religion and distinguish its forms: atheism (denial of God's existence), agnosticism (the claim that God's existence is unknown or unknowable), humanism (an ethical worldview grounded in human reason and welfare without the supernatural), and secularism (the principle of state neutrality toward religion, not the absence of belief). Know the rise of the "no religion" category in Australian census data, and the reasons offered: secularisation, scientific rationalism, pluralism, institutional distrust, and generational change. Understand that non-religious belief systems can perform similar functions to religion - ethics, community, ritual, meaning-making - and that they relate to religion through dialogue, critique and coexistence.
Traps
Do not use "atheist", "agnostic" and "non-religious" interchangeably. Avoid treating secularism as hostility to religion; it is about state neutrality. A frequent error is claiming non-religious people lack ethics; humanism offers a developed moral framework. Another trap is assuming the "no religion" census category means atheism - it includes indifference and spiritual-but-not-religious positions.
Worked example
Question: "Distinguish atheism, agnosticism and humanism." A strong answer defines each precisely, notes that atheism concerns belief in God while humanism concerns ethics, and gives an example such as a humanist celebrant conducting a secular funeral. Rule of thumb: define each term, then show where they overlap and where they do not.
Rule of thumb
Separate belief about God from ethical framework from state policy.
