Know or listen to those who know.
We know accurately only when we know little; with knowledge, doubt increases.
Without the art of living knowledge nought avails.
The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
All I know is that I know nothing.
Mistakes are, after all, the foundations of truth, and if a man does not know what a thing is, it is at least an increase in knowledge if he knows what it is not.
Knowing is not enough; we must apply. Willing is not enough; we must do.
Few people know how to be old.
Dare to be wise, begin!

Men should strive to think much and know little.
Knowledge is power.
Imagination is more important than knowledge.
Science is organized knowledge. Wisdom is organized life.
I know that I know nothing.
He who knows does not speak; he who speaks does not know.
Doubt is not below knowledge, but above it.
Not only were we happy, but we knew it.
Everyone's responsibility involves two acts: wanting to know and daring to say.
We can never know what to want, because, living only one life, we can neither compare it with our previous lives nor perfect it in our lives to comes.
Man knows much more than he understands.
To know much is often the cause of doubting more.
To know is to know that one knows.
One does not know completely a science as long as one does not know its history.
Sunshine cannot bleach the snow, Nor time unmake what poets know.
Of all the sciences needful for men, the chief one is the knowledge of how to live, doing as little harm as possible; and of all arts, the most important is that which teaches how to avoid evil, and how to produce good with the least violence.
Most teachers waste their time by asking questions which are intended to discover what a pupil does not know, whereas the true art of questioning has for its purpose to discover what the pupil knows or is capable of knowing.
He knows the universe, and himself he does not know.
Science is what you know, philosophy is what you don't know.
What can I know? What ought I to do? What can I hope?
The main scourge of humanity is not ignorance, because the ignorant often have excuses, but the refusal to know.
