Albert Pike,
Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry
“ If the obligation is absolute, it is immutable and universal. For if what is obligation to-day may not be so to-morrow, if what is obligatory for me may not be so for you, the obligation differing from itself, it would be relative and contingent. This fact of absolute, immutable, universal obligation is certain and manifest. The good is the foundation of obligation. If it be not, obligation has no foundation ”
