Confusing Words
objective vs absolute vs relative
These three adjectives are essential to critical thinking and appear frequently in philosophical, scientific and literary discussions.
- objective — objective not influenced by personal feelings or opinions; based on observable facts that exist independently of the viewer; for example, ‘An objective assessment of the data requires setting aside personal beliefs and prior assumptions.’
- absolute — absolute not qualified or dependent on anything else; complete and unconditional; for example, ‘The philosopher argued that there are no absolute moral truths — all ethical judgements are shaped by historical and cultural context.’
- relative — relative considered in relation to or compared with something else; not independent or fixed; for example, ‘What constitutes poverty is relative — its meaning differs significantly across different countries and time periods.’
Memory rule: A useful triangle: 'objective' is about independence from personal bias; 'absolute' is about being unconditional and complete; 'relative' is about being dependent on context for meaning. These concepts are often used together in philosophy and critical analysis — for example, debating whether moral truths are absolute, relative or objective.
