‘God’s Hotel’ by Victoria Sweet: A Profoundly Human Book

0

A book that can delight you through its entertainments or instruct you with useful knowledge is a good book; one that does both is a great book. Rarely, a book comes along that not only instructs and delights but also deepens your humanity, carving out extra space inside us to carry even more compassion. God’s Hotel by Victoria Sweet is such a book. [A hat-tip to Jesse Kornbluth of Head Butler for introducing me to it.]

There were many reasons I enjoyed this book, which is really many books at once:

1) The author, Dr Victoria Sweet, who has a PhD in medieval history as well as an MD, shares the ancient Latin and Greek etymologies of many terms used in patient care today. Hospitality, community, charity – what do they really mean? Through her stories about her time taking care of patients, Dr Sweet shows how those formed the three foundational principles of Laguna Honda Hospital.

Hospital comes from hospitality, the root of which is hospes, which means both ‘guest’ or ‘host’. This is how Sweet explains this:

What I learned at SXSW 2012

1

I recently got back from the South By Southwest Conference and had a marvelous time. One unusual thing that happened this time around was that several people asked me, “Why are you here?”  It was a bit like asking why do you drink water, or what’s the big deal about this whole breathing thing anyway.

And yet, a trivial question it is not.  In fact, I very nearly didn’t go this year, so it’s important for me to remind myself why I do take 6 days off from work, buy a non-cheap pass, pay for non-cheap airfare and scrounge for accommodations in an overstuffed Austin during the second week of March every year to go to SXSW Interactive (NB: to add the Film and Music portions would frankly be too much). Here are my five reasons:

1) Encountering new ideas.  SXSW consistently pulls to its stages some of greatest minds in science, business, technology, entrepreneurship, journalism and all-around awesomeness.  Because there are so many stages, these speakers have incentive to share their best work with us lest we leave for another of the 35-40 simultaneous talks.  This year alone, I was lucky to catch talks by neuroscientist David Eagleman, inventor Dean Kamen, game designer Jane McGonigal, Mathematica creator Stephen Wolfram, and X Prize founder Peter Diamandis (about all of whom I will share below).

Notes from a great conference

1

I just came out of a four-day conference (which shall remain nameless), and it was such a life-affirming, mind-expanding, invigorating experience that I thought I would share my notes.  I got doused by a downpour of novel ideas from disparate fields in the many talks I attended.  Here’s a sampling, in no particular order:

What are the chances of your coming into being?

A little while ago I had the privilege of attending TEDx San Francisco, organized by the incomparable Christine Mason McCaull.  One of the talks was by Mel Robbins, a riotously funny self-help author and life coach with a syndicated radio show.  In it, she mentioned that scientists calculate the probability of your existing as you, today, at about one in 400 trillion (4×1014).

“That’s a pretty big number,” I thought to myself.  If I had 400 trillion pennies to my name, I could probably retire.

Previously, I had heard the Buddhist version of the probability of ‘this precious incarnation’.  Imagine there was one life preserver thrown somewhere in some ocean and there is exactly one turtle in all of these oceans, swimming underwater somewhere.  The probability that you came about and exist today is the same as that turtle sticking its head out of the water — in the middle of that life preserver.  On one try.

So I got curious: are either of these numbers correct?  Which one’s bigger?  Are they gross exaggerations?  Or is it possible that they underestimate the true number?

First, let us figure out the probability of one turtle sticking its head out of the one life preserver we toss out somewhere in the ocean.  That’s a pretty straightforward calculation.

According to WolframAlpha, the total area of oceans in the world is 3.409×108 square kilometers, or 340,900,000 km2 (131.6 million square miles, for those benighted souls who still cling to user-hostile British measures).  Let’s say a life preserver’s hole is about 80cm in diameter, which would make
