Consider the hummingbird for a long moment.  A hummingbird’s heart beats ten times a second.  A hummingbird’s heart is the size of a pencil eraser.  A hummingbird’s heart is a lot of the hummingbird.  Joyas voladoras, flying jewels, the first white explorers in the Americas called them…
Each one visits a thousand flowers a day.  They can dive at sixty miles an hour.  They can fly backwards.  They can fly more than five hundred miles without pausing to rest.  But when they rest they come close to death:  on frigid nights, or when they are starving, they retreat into torpor, their metabolic rate slowing to a fifteenth of their normal sleep rate, their hearts sludging nearly to a halt, barely beating, and if they are not soon warmed, if they do not soon find that which is sweet, their hearts grow cold, and they cease to be.
Hummingbirds, like all flying birds but more so, have incredible enormous immense ferocious metabolisms.  To drive those metabolisms they have race-car hearts that eat oxygen at an eye-popping rate.  Their hearts are built of thinner, leaner fibers than ours. Their arteries are stiffer and more taut.  They have more mitochondria in their heart muscles — anything to gulp more oxygen.  Their hearts are stripped to the skin for the war against gravity and inertia, the mad search for food, the insane idea of flight.  The price of their ambition is a life closer to death; they suffer more heart attacks and aneurysms and ruptures than any other living creature.  It’s expensive to fly. You burn out.  You fry the machine.  You melt the engine.  Every creature on earth has approximately two billion heartbeats to spend in a lifetime.  You can spend them slowly, like a tortoise and live to be two hundred years old, or you can spend them fast, like a hummingbird, and live to be two years old.

I doubt very much if it is possible to teach anyone to understand anything, that is to say, to see how various parts of it relate to all the other parts, to have a model of the structure in one’s mind.  We can give other people names, and lists, but we cannot give them our mental structures;  they must build their own.

Since we can’t know what knowledge will be most needed in the future, it is senseless to try to teach it in advance.
Instead, we should try to turn out people who love learning so much and learn so well that they will be able to learn what needs to be learned.

The First Amendment to the United States Constitution encourages a diversity of religions but does not prohibit criticism of religion.  In fact it protects and encourages criticism of religion.  Religions ought to be subject to at least the same degree of skepticism as, for example, contentions about UFO visitations or Velikovskian catastrophism.  I think it is healthy for the religions themselves to foster skepticism about the fundamental underpinnings of their evidential bases.  There is no question that religion provides a solace and support, a bulwark in time of emotional need, and can serve extremely useful social roles.  But it by no means follows that religion should be immune from testing, from critical scrutiny, from skepticism.  It is striking how little skeptical discussion of religion there is in the nation that Tom Paine, the author of The Age of Reason, helped to found.  I hold that belief systems that cannot survive scrutiny are probably not worth having.

Beware:
Ignorance
Protects itself.
Ignorance
Promotes suspicion.
Suspicion
Engenders fear.
Fear quails,
Irrational and blind,
Or fear looms,
Defiant and closed.
Blind, closed,
Suspicious, afraid,
Ignorance
Protects itself,
And protected,
Ignorance grows.

Every revolutionary idea seems to evoke three stages of reaction.  They may be summed up by the phrases:  1)  It’s completely impossible.  2)  It’s possible, but it’s not worth doing.  3)  I said it was a good idea all along.
 
    —    Arthur C. Clark
 
It has been said that the reception of any successful new scientific hypothesis goes through three predictable phases before being accepted.
First, it is criticized for being untrue.
Secondly, after supporting evidence accumulates, it is stated that it may be true, but it is not particularly relevant.
Thirdly, after it has clearly influenced the field, it is admitted to be true and relevant, but the same critics assert that the idea was not original.
 
    —    Adrienne Zihlman
 
All truth passes through three stages:  First, it is ridiculed.  Second, it is violently opposed.  Third, it is accepted as self-evident.
 
    —    Arthur Schopenhauer
 
[We are stuck between “One” and “Two”, so we may never get to “Three”…  It strikes me that we simply lack the moral fiber to recognize the truth and the political leadership to address the issues.    —    kmab]

Why do I read?
I just can’t help myself.
I read to learn and to grow, to laugh
and to be motivated.
I read to understand things I’ve never
been exposed to.
I read when I’m crabby, when I’ve just
said monumentally dumb things to the
people I love.
I read for strength to help me when I
feel broken, discouraged, and afraid.
I read when I’m angry at the whole
world.
I read when everything is going right.
I read to find hope.
I read because I’m made up not just of
skin and bones, of sights, feelings,
and a deep need for chocolate, but I’m
also made up of words.
Words describe my thoughts and what’s
hidden in my heart.
Words are alive — when I’ve found a
story that I love, I read it again and
again, like playing a favorite song
over and over.
Reading isn’t passive — I enter the
story with the characters, breathe
their air, feel their frustrations,
scream at them to stop when they’re
about to do something stupid, cry with
them, laugh with them.
Reading for me, is spending time with a
friend.
A book is a friend.
You can never have too many.
