We're responsible for each other

My friend lost his brother yesterday and posted the following on Facebook. He's a brilliant guy, and his thoughts on what it means to live in a connected world should be required reading for everyone. 

My brother Rob died this morning. His death has reminded me of a belief that I hold loosely on better days, and deeply on days like today: We're responsible for each other. If your politics or your personal philosophy makes you recoil from that notion writ large, then accept that we're responsible for our loved ones, at least; and understand that you'll find no comfort in the excuse that it was inconvenient to help a brother in need, or in the belief that help wasn't warranted because of his failings or because your scruples wouldn't abide it. Risk all to meet your responsibility, and hope that others are willing to risk all to meet theirs. Everything else is mere conceit.
