Tao Te Ching

Seventy-One

Knowing ignorance in strength.
Ignoring knowledge is sickness.

If one is sick of sickness, then one is not sick.
The sage is not sick because he is sick of sickness.
Therefore he is not sick.

To me it says not only that knowledge is power, but that if a person has no desire to learn about the things they should know, then there is something fundamentally wrong with them.

It also seems to me to suggest that if you do not suffer fools gladly, then you would be well served to be knowledgeable about your own affairs, lest you be thought a fool as well.
