Bug Out Books And The Bedrock Of The Next Civilization

So all of the Doomsaying that I’ve been writing about has had my wife and I going back and forth on a few things, one of which is the absolute must-have books that may not be come by easily in the post-apocalypse.
While I myself don’t envision books – physical or electronic – going away, it’s an interesting thought experiment that we’ve been trading back and forth on for a few days.
The premise: You have limited space, what are the absolutely crucial 30 books you need to help lay a foundation for your posterity.
I like this list because it isn’t so much about “best” or “most important” but about the books that best exemplify the things we only wish to carry forward. This means that, instead of the entire collected works of Shakespeare, maybe we just take a couple of the tragedies, a couple of the comedies, and squeeze enough room for Milton, Kierkegaard and Aquinas instead of letting 12th Night collect dust on the shelf.
It also maybe means including books that are by no means the “best” of anything, but perhaps will help illustrate the seeds of our current decline as a warning shot to our posterity; books such as Writing and Difference or Das Kapital for example, though I will not put those on my list.
I don’t know.
The wife is currently composing her list.
Here is mine, in no particular order:

1) Paradise Lost – John Milton
2) René Descartes’s Principles of Philosophy, Demonstrated According to the Geometric Method – Benedict de Spinoza
3) Huckleberry Finn – Mark Twain
4) Puddin’head Wilson And Those Extraordinary Twins – Mark Twain
5) On General Relativity – Albert Einstein
6) The Divine Comedy – Dante Alighieri
7) Summa Theologica – Thomas Aquinas
8) Macbeth – William Shakespeare
9) Hamlet – William Shakespeare
10) As I Lay Dying – William Faulkner
11) The Principia: Mathematical Principles of Natural Philosophy – Isaac Newton
12) The History of the Decline and Fall of the Roman Empire — Edward Gibbon
13) The History of the Peloponnesian War – Thucydides
14) Man, Economy & State – Murray Rothbard
15) Discipline & Punish – Michel Foucault
16) Moby Dick – Herman Melville
17) Critique of Pure Reason – Immanuel Kant
18) The Journals of Soren Kierkegaard – Soren Kierkegaard
19) The Gay Science – Friedrich Nietzsche
20) Twice-Told Tales – Nathaniel Hawthorne
21) Wealth of Nations – Adam Smith
22) Hitchhiker’s Guide to the Galaxy – Douglas Adams
23) The Three Musketeers – Alexander Dumas
24) Nova Scientia* – Niccolo Tartaglia
25) First Principles of Atomic Physics – Richard Franklin Humphreys, Robert Beringer
26) The Complete Short Story Collection of Edgar Allen Poe – Edgar Allen Poe
27) Poetics – Aristotle
28) Illiad/Oddessy – Homer
29) Aeneid – Virgil
30) The Big Sleep – Raymond Chandler
30a) Tishomingo Blues – Elmore Leonard

Not cheating. I’ll just stuff that last one in my ruck or something. It’s barely larger than a deck of cards, for fuck’s sake.
Anyway.
When the wife is done, I’ll throw her list up here. If you want to denigrate any of my choices and offer your own suggestions, please feel free to do so. If you would like me to explain or defend a particular selection(s), ask and I will do so.
Note: I don’t count books like the Bible in this. Obviously you’re making room for your doctrinal religious texts. Also note: this doesn’t count how-to or repair manuals, blueprints, survival guides, field manuals or anything else designed to get you through the day-to-day. I assume you’ve already cleared a space in your head or home for whatever you need in that area.
This exercise is about laying foundations for tomorrow, not getting through today.
* This is a must-read for anyone interested ballistics. Tartaglia was tasked with finding the maximum potential range of Italian military artillery. What he discovered was a new type of math, laying the groundwork for everything Galileo would later “discover” through his experiments on falling bodies. This book contains all of the fundamentals on modern ballistics, chronicles the development of the Gunner’s Quadrant, and includes ballistics tables for every gun in the known world at the time**.
** Admittedly, 16th century Europe wasn’t exactly awash in guns.
