一种理解是，教育的意义在于教人如何思考。但美国作家大卫·福斯特·华莱士（David Foster Wallace）在他字字珠玑的「This is Water」毕业演讲中，说他不认同这种陈词滥调。
There are these two guys sitting together in a bar in the remote Alaskan wilderness. One of the guys is religious, the other is an atheist, and the two are arguing about the existence of God with that special intensity that comes after about the fourth beer. And the atheist says: “Look, it’s not like I don’t have actual reasons for not believing in God. It’s not like I haven’t ever experimented with the whole God and prayer thing. Just last month I got caught away from the camp in that terrible blizzard, and I was totally lost and I couldn’t see a thing, and it was 50 below, and so I tried it: I fell to my knees in the snow and cried out ‘Oh, God, if there is a God, I’m lost in this blizzard, and I’m gonna die if you don’t help me.’” And now, in the bar, the religious guy looks at the atheist all puzzled. “Well then you must believe now,” he says, “After all, here you are, alive.” The atheist just rolls his eyes. “No, man, all that was was a couple Eskimos happened to come wandering by and showed me the way back to camp.”
另一个例子是，人们常说「You only live once」，所以你要去冒险。但这句话也可以从反面理解——你只能活一次，所以你要避免出局。
[…] this is one part of what teaching me how to think is really supposed to mean. To be just a little less arrogant. To have just a little critical awareness about myself and my certainties. Because a huge percentage of the stuff that I tend to be automatically certain of is, it turns out, totally wrong and deluded. I have learned this the hard way, as I predict you graduates will, too.
Probably the most dangerous thing about an academic education–least in my own case–is that it enables my tendency to over-intellectualise stuff, to get lost in abstract argument inside my head, instead of simply paying attention to what is going on right in front of me, paying attention to what is going on inside me.
And the compelling reason for maybe choosing some sort of god or spiritual-type thing to worship–be it JC or Allah, be it YHWH or the Wiccan Mother Goddess, or the Four Noble Truths, or some inviolable set of ethical principles–is that pretty much anything else you worship will eat you alive. If you worship money and things, if they are where you tap real meaning in life, then you will never have enough, never feel you have enough. It’s the truth. Worship your body and beauty and sexual allure and you will always feel ugly. And when time and age start showing, you will die a million deaths before they finally grieve you. On one level, we all know this stuff already. It’s been codified as myths, proverbs, clichés, epigrams, parables; the skeleton of every great story. The whole trick is keeping the truth up front in daily consciousness.
The really important kind of freedom involves attention and awareness and discipline, and being able truly to care about other people and to sacrifice for them over and over in myriad petty, unsexy ways every day.
That is real freedom. That is being educated, and understanding how to think. The alternative is unconsciousness, the default setting, the rat race, the constant gnawing sense of having had, and lost, some infinite thing.
