Here the free spirit of mankind, at length,
Throws its last fetters off; and who shall place

Or curb his swiftness in the forward race?

I know but one freedom and that is the freedom of the mind.
 Antoine de Saint-Exupéry
Freedom is not worth having if it does not connote freedom to err.
The amount of happiness that you have depends on the amount of freedom you have in your heart.
 Thích Nhất Hạnh
Without freedom of thought, there can be no such thing as wisdom - and no such thing as public liberty without freedom of speech.

Quotes from the same author

Of shining ones.
 William C. Bryant
Can anything be imagined more abhorrent to every sentiment of generosity and justice, than the law which arms the rich with the legal right to fix, by assize, the wages of the poor? If this is not slavery, we have forgotten its definition. Strike the right of associating for the sale of labor from the privileges of a freeman, and you may as well bind him to a master, or ascribe him to the soil.
 William C. Bryant
The summer day is closed - the sun is set: Well they have done their office, those bright hours, The latest of whose train goes softly out In the red west. The green blade of the ground Has risen, and herds have cropped it; the young twig Has spread its plaited tissues to the sun; Flowers of the garden and the waste have blown And withered; seeds have fallen upon the soil, From bursting cells, and in their graves await Their resurrection. Insects from the pools Have filled the air awhile with humming wings, That now are still for ever; painted moths Have wandered the blue sky, and died again
 William C. Bryant
I gazed upon the glorious sky And the green mountains round, And thought that when I came to lie At rest within the ground, 'Twere pleasant, that in flowery June When brooks send up a cheerful tune, And groves a joyous sound, The sexton's hand, my grave to make, The rich, green mountain-turf should break.
 William C. Bryant
Thou who wouldst see the lovely and the wild Mingled in harmony on Nature's face, Ascend our rocky mountains. Let thy foot Fail not with weariness, for on their tops The beauty and the majesty of earth, Spread wide beneath, shall make thee to forget The steep and toilsome way.
