To all new truths, or renovation of old truths, it must be as in the ark between the destroyed and the about-to-be renovated world. The raven must be sent out before the dove, and ominous controversy must precede peace and the olive wreath.
Therefore, be ye lamps unto yourselves, be ye a refuge to yourselves. Hold fast to the truth as a lamp; hold fast as a refuge to the truth. Look not for refuge to anyone besides yourselves.
New opinions often appear first as jokes and fancies, then as blasphemies and treason, then as questions open to discussion, and finally as established truths.
On love, not harming others, and respecting all beings. Even animals have these elements in their behavioral patterns. We should start by observing how animals act. They are honest and appreciate it when we are honest with them. If you present something nice to an animal in one hand while hiding a rope in the other, the creature will know your intention. Yet animals have no religion, no constitution. Basic nature has endowed them with the faculty of discernment. It is the same for humans.
...And these vicissitudes come best in youth;
For when they happen at a riper age,
People are apt to blame the Fates, forsooth,
And wonder Providence is not more sage.
Adversity is the first path to truth:
He who hath proved war, storm, or woman's rage,
Whether his winters be eighteen or eighty,
Has won experience which is deem'd so weighty.
