A central lesson of science is that to understand complex issues (or even simple ones), we must try to free our minds of dogma and to guarantee the freedom to publish, to contradict, and to experiment. Arguments from authority are unacceptable.
And for a disciple thus freed, in whose heart dwells peace, there is nothing to be added to what has been done, and naught more remains for him to do. Just as a rock of one solid mass remains unshaken by the wind, even so, neither forms, nor sounds, nor odors, nor tastes, nor contacts of any kind, neither the desired, nor the undesired, can cause such an one to waver. Steadfast is his mind, gained is deliverance.
We attain freedom as we let go of whatever does not reflect our magnificence. A bird cannot fly high or far with a stone tied to its back. But release the impediment, and we are free to soar to unprecedented heights.
As a nation, we began by declaring that 'all men are created equal.' We now practically read it 'all men are created equal, except negroes.' When the Know-Nothings get control, it will read 'all men are created equal, except negroes, and foreigners, and Catholics.' When it comes to this I should prefer emigrating to some country where they make no pretense of loving liberty – to Russia, for instance, where despotism can be taken pure, and without the base alloy of hypocrisy.
