Uncertainty will always be part of the taking charge process.

The quest for certainty blocks the search for meaning. Uncertainty is the very condition to impel man to unfold his powers.

Education is the process of leading people from cocksure ignorance to thoughtful uncertainty.

The essence of romance is uncertainty.

To face the inevitable is to confront something sacred. As long as anything is uncertain, the roads are open in more than one direction, and right and wrong may have many aspects. But let the issue be determined, let the die be cast, and acceptance and adjustment become our immediate duty. Until God’s will be known, we may work and wrestle and pry to carry our point, to save the day, to win the prize, spurred only the more by the uncertainty; of the result. But let the result be known, however dark and disappointing, and we should view it in the light of God’s plan to make us His evident children, and ask what we are to learn, what next we are to do.

Metaphysics, or the attempt to conceive the world as a whole by means of thought, has been developed, from the first, by the union and conflict of two very different human impulses, the one urging men towards mysticism, the other urging them towards science... But the greatest men who have been philosophers have felt the need both of science and mysticism: the attempt to harmonize the two was what made their life, and what always must, for all its arduous uncertainty, make philosophy, to some minds, a greater thing than either science or religion.

The value of philosophy is to be sought largely in its very uncertainty. He who has no tincture of philosophy goes through life imprisoned in the prejudices derived from common sense, from the habitual beliefs of his age or his nation, and from convictions which have grown up in his mind without the cooperation or consent of his deliberate reason. As soon as we begin to philosophize, on the contrary, we find that even the most everyday things lead to problems to which only very incomplete answers can be given. Philosophy, though unable to tell us with certainty what is the true answer to the doubts which it raises, is able to suggest many possibilities which enlarge our thought and free them from the tyranny of custom.

To teach how to live with uncertainty, and yet without being paralyzed by hesitation, is perhaps the chief thing that philosophy in our age can still do for those who study it.

The instinct of conventionality, horror of uncertainty, and vested interests, all militate against the acceptance of a new idea.

We desire truth, and find within ourselves only uncertainty. We seek happiness, and find only misery and death.

What a chimera is man! what a confused chaos! what a subject of contradiction! a professed judge of all things, and ;yet a feeble worm of the earth! the great depository and guardian of truth, and yet a mere huddle of uncertainty! the glory and the scandal of the universe!

We desire the truth, but find within ourselves nothing but uncertainty. We seek happiness, but find mainly misery. We are incapable of suppressing the desire for truth and happiness, and yet are incapable of knowing truth and happiness. These frustrated desires remind us how far we have fallen from our true state.

Truth is strengthened by observation and time, pretenses by haste and uncertainty.

The longest journey is the journey inwards. Of him who has chosen his destiny, who has started upon his quest for the source of his being (Is there a source?). He is still with you, but without relation, isolated in your feeling like one condemned to death or one whom imminent farewell prematurely dedicates to the loneliness which is the final lot of all. Between you and him is distance, uncertainty - care.

A clear stream reflects all the objects on its shore, but is unsullied by them; so it should be with our hearts; they should show the effect of all earthly objects, but remain unstained by any... All worldly things are so much without us, and so subject to variety and uncertainty, that they do not make us when they come, nor mend us while they stay, nor undo us when they are taken away.

The mind-expanding discovery of quantum mechanics is that Newtonian physics does not apply to subatomic phenomena... We cannot know both the position and the momentum of a particle with absolute precision... This is Werner Heisenberg's uncertainty principle.

Nothing is certain, but uncertainty.

Wisdom means keeping a sense of the fallibility of all our views and opinions, and of the uncertainty and instability of the things we most count on.

Human knowledge is personal and responsible, an unending adventure at the edge of uncertainty.
