our republican ideas cannot be consistently carried out while women are excluded from any share in the government. ... Any class of human beings to whom a position of perpetual subordination is assigned, however much they may be petted and flattered, must inevitably be dwarfed, morally and intellectually.

A reformer is one who sets forth cheerfully toward sure defeat.

So easy it is to see the errors of past ages, so difficult to acknowledge our own!

Even if nothing worse than wasted mental effort could be laid to the charge of theology, that alone ought to be sufficient to banish it from the earth ... What a vast amount of labour and learning has been expended, as uselessly as emptying shallow puddles into sieves! How much intellect has been employed mousing after texts, to sustain preconceived doctrines!

In the first place, the government ought not to be invested with power to control the affections, any more than the consciences of citizens.

The existence of very pious feelings, in conjunction with intolerance, cruelty, and selfish policy, has never ceased to surprise and perplex those who have viewed it calmly from a distance. ...

What destruction of the beautiful monuments of past ages, what waste of life, what disturbance of domestic and social happiness, what perverted feelings, what blighted hearts, have always marked its baneful progress!

the excess of all good things is mischievous.
