“The Exclusion Principle is laid down purely for the benefit of the electrons themselves, who might be corrupted (and become dragons or demons) if allowed to associate too freely.”

Context: There are people who are excitable by nature and allow themselves to become angry for the most trivial of reasons. Judo can help such people learn to control themselves. Through training, they quickly realize that anger is a waste of energy, that it has only negative effects on the self and others.

As quoted in The Quotable Politician (2003) by William B. Whitman, p. 30.

Woman in the Nineteenth Century (1845)
Context: We would have every arbitrary barrier thrown down. We would have every path laid open to Woman as freely as to Man. Were this done, and a slight temporary fermentation allowed to subside, we should see crystallizations more pure and of more various beauty. We believe the divine energy would pervade nature to a degree unknown in the history of former ages, and that no discordant collision, but a ravishing harmony of the spheres, would ensue.
Yet, then and only then will mankind be ripe for this, when inward and outward freedom for Woman as much as for Man shall be acknowledged as a right, not yielded as a concession.
