The price of anything is the amount of life you exchange for it.
Henry David Thoreau
The essence of being human is that one does not seek perfection that one is prepared in the end to be defeated and broken up by life, which is the inevitable price of fastening one's love upon other human individuals.
These days man knows the price of everything, but the value of nothing.
If physical death is the price that I must pay to free my white brothers and sisters from a permanent death of the spirit, then nothing can be more redemptive.
Martin Luther King Jr.
