In practice there are ‘absolutes in the conventional sense’
Absolute may refer to:
Science[edit]
Absolute magnitude, the brightness of a star
Absolute zero, the lower limit of the thermodynamic temperature scale, -273.15 °C
Mathematics[edit]
Absoluteness in mathematical logic
Absolute value, a notion in mathematics, commonly a number’s numerical value without regard to its sign
Absolute (geometry), the quadric at infinity
Law[edit]
Absolute defence, a factual circumstance or argument that, if proven, will end the litigation in favor of the defendant
Absolute liability, a standard of legal liability found in tort and criminal law of various legal jurisdictions
Politics[edit]
Absolute majority, a majority of the entire membership of a group
Absolute monarchy, a monarchical form of government in which the monarch’s powers are not limited by a constitution or by the law
Linguistics[edit]
Absolute construction, a grammatical construction used in certain languages
Philosophy[edit]
Absolute (philosophy), a concept in philosophy
Absolute truth (Buddhism) (Sanskrit, paramārtha-satya, Pāli paramattha sacca, Tibetan: don-dam bden-pa), describes the ultimate reality as “sunyata”, empty of concrete and inherent characteristics
When I say,
Within a very sound philosophical framework I am absolutely certain there is no such thing as Absolute Truth.
Note the “Truth” is with a capital ‘T’ i.e. the ontological Truth and some claim to be God. This is the Truth of the Absolutely Absolute.
When I refer to “absolute moral principles” I was referring to relative absolutes within the Moral and Ethical Framework. Such absolutes are conditional upon whatever their framework and system of knowledge, thus they are relative absolutes.
From my perspective, in term of degrees of philosophical complexity, “absolute moral principles” would be rated at 99% while the others are below it.
