“One special advantage of the skeptical attitude of mind is that a man is never vexed to find that after all he has been in the wrong.”
Whenever one tries to suppress doubt, there is tyranny.
Reserve your right to think, for even to think wrongly is better than not to think at all.
Here the ways of men part: if you wish to strive for peace of soul and pleasure, then believe; if you wish to be a devotee of truth, then inquire.
Read not to contradict and confute; nor to believe and take for granted; nor to find talk and discourse; but to weigh and consider.
Stubborn and ardent clinging to one's opinion is the best proof of stupidity.
How easy it is to repel and to wipe away every impression which is troublesome or unsuitable, and immediately to be in all tranquility.
If your mind is empty, it is always ready for anything, it is open to everything.
The important thing is not to stop questioning. Curiosity has its own reason for existence. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery each day. Never lose a holy curiosity. ... Don't stop to marvel.
Be not afraid of life. Believe that life is worth living, and your belief will help create the fact.
For nonconformity the world whips you with its displeasure. And therefore a man must know how to estimate a sour face.
I believe that the extraordinary should certainly be pursued. But extraordinary claims require extraordinary evidence.
Re-examine all you have been told. Dismiss whatever insults your own soul.
When another blames you or hates you, or people voice similar criticisms, go to their souls, penetrate inside and see what sort of people they are. You will realize that there is no need to be racked with anxiety that they should hold any particular opinion about you.
Wonder is the beginning of wisdom.
If anyone tells you that a certain person speaks ill of you, do not make excuses about what is said of you, but answer: He was ignorant of my other faults, else he would not have mentioned these alone.
The unexamined life is not worth living.
The only true wisdom is in knowing you know nothing.
The fault is in the one who blames. Spirit sees nothing to criticize.
I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but I'm not absolutely sure of anything. There are many things I don't know anything about, such as whether it means anything to ask "Why are we here?" I might think about it a little bit, and if I can't figure it out then I go on to something else. But I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose — which is the way it really is, as far as I can tell. Possibly. It doesn't frighten me.
He who remembers the evils he has undergone, and those that have threatened him, and the slight causes that have changed him from one state to another, prepares himself in that way for future changes and for recognizing his condition. The life of Caesar has no more to show us than our own; an emperor's or an ordinary man's, it is still a life subject to all human accidents.
If thou desire to profit, read with humility, simplicity, and faithfulness; nor even desire the repute of learning.
If you want to improve, be content to be thought foolish and stupid.
Not-knowing is true knowledge. Presuming to know is a disease.
Do not go by revelation; Do not go by tradition; Do not go by hearsay; Do not go on the authority of sacred texts; Do not go on the grounds of pure logic; Do not go by a view that seems rational; Do not go by reflecting on mere appearances; Do not go along with a considered view because you agree with it; Do not go along on the grounds that the person is competent; Do not go along because "the recluse is our teacher." Kalamas, when you yourselves know: These things are unwholesome, these things are blameworthy; these things are censured by the wise; and when undertaken and observed, these things lead to harm and ill, abandon them... Kalamas, when you know for yourselves: These are wholesome; these things are not blameworthy; these things are praised by the wise; undertaken and observed, these things lead to benefit and happiness, having undertaken them, abide in them.
It is not a dream, it is a simple feat of scientific electrical engineering, only expensive — blind, faint-hearted, doubting world! . . . Humanity is not yet sufficiently advanced to be willingly led by the discover's keen searching sense. But who knows? Perhaps it is better in this present world of ours that a revolutionary idea or invention instead of being helped and patted, be hampered and ill-treated in its adolescence — by want of means, by selfish interest, pedantry, stupidity and ignorance; that it be attacked and stifled; that it pass through bitter trials and tribulations, through the heartless strife of commercial existence. So do we get our light. So all that was great in the past was ridiculed, condemned, combated, suppressed — only to emerge all the more powerfully, all the more triumphantly from the struggle.
