No, if there's any ultimate redemption, it would be because I passed though your life without scarring you, and did not diminish who you are.

There are thousands of proteins in the cells, some of them very large chains of molecules. And the cell doesn't function if one of those chains of molecules isn't there, and you start looking at the complexity of life and the mystery of life, and then start thinking about things like the twenty universal constants, that if any one of them from Plank's minimum to the mass of a proton, if one of them is the tiniest bit off, there would be no life or possibility of it in the universe.

I imagined a life that turned out to be pretty much exactly like the one I've had. That fascinates me endlessly. I wake up many mornings, and it almost wouldn't surprise me if I woke up from it and it was all a dream.

One of the greatest gifts we receive from dogs is the tenderness they evoke in us. The disappointments of life, the injustices, the battering events that are beyond our control, and the betrayals we endure, from those we befriended and loved, can make us cynical and turn our hearts into flint – on which only the matches of anger and bitterness can be struck into flame. By their delight in being with us, the reliable sunniness of their disposition, the joy they bring to playtime, the curiosity with which they embrace each new experience, dogs can melt cynicism,and sweeten the bitter heart.

The hatred of truth is the taproot of violence.

Every life is complicated, every mind a kingdom of unmapped mysteries.
