Wisdom of Poety?
When Shelley writes “our calculations have outrun our conception; we have eaten more than we can digest,” it is hard to believe that he was writing early in the nineteenth century and not early in the twenty-first. For when he claims “man, having enslaved the elements, remains himself a slave,” he seems to have captured perfectly the great threat of modern technology in our day. Shelley leaves us with a sobering sense of the dangers of a scientific wisdom completely severed from poetic wisdom. As his wife’s portrait of Victor Frankenstein suggests, such a liberated science may lead to a new kind of slavery, as human beings lose control of the products of their technological imagination, and perhaps end up serving the very forces that were meant to serve them.

Rudyard Kipling
If

If you can keep your head when all about you
Are losing theirs and blaming it on you;
If you can trust yourself when all men doubt you,
But make allowance for their doubting too;
If you can wait and not be tired by waiting,
Or, being lied about, don't deal in lies,
Or, being hated, don't give way to hating,
And yet don't look too good, nor talk too wise;

If you can dream - and not make dreams your master;
If you can think - and not make thoughts your aim;
If you can meet with triumph and disaster
And treat those two imposters just the same;
If you can bear to hear the truth you've spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to broken,
And stoop and build 'em up with wornout tools;

If you can make one heap of all your winnings
And risk it on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breath a word about your loss;
If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: "Hold on";

If you can talk with crowds and keep your virtue,
Or walk with kings - nor lose the common touch;
If neither foes nor loving friends can hurt you;
If all men count with you, but none too much;
If you can fill the unforgiving minute
With sixty seconds' worth of distance run -
Yours is the Earth and everything that's in it,
And - which is more - you'll be a Man my son!

What is critical thinking?
Nobody said it better than Francis Bacon, back in 1605:

For myself, I found that I was fitted for nothing so well as for the study of Truth; as having a mind nimble and versatile enough to catch the resemblances of things … and at the same time steady enough to fix and distinguish their subtler differences; as being gifted by nature with desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and as being a man that neither affects what is new nor admires what is old, and that hates every kind of imposture.
