Relative vs. Absolute
Depending on context versus independent of context.
The comparisoni
“The speed of light is absolute — it's constant for every observer. That's the counterintuitive piece of special relativity.”
The ruleii
¶
RELATIVE = context-dependent. ABSOLUTE = fixed.
RELATIVE means it depends on the frame of reference — "tall" is relative to what you compare. ABSOLUTE means it holds regardless of context — e.g. mathematical truths, the speed of light. Philosophy argues which moral claims are which.
Memory aidiii
Remember it like this
Relative = it depends. Absolute = it doesn't.
