An objective uncertainty held fast in an appropriation-process of the most passionate inwardness is the truth, the highest truth attainable for an existing individual.

We live between two dense clouds the forgetting of what was and the uncertainty of what will be.

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

If subjectivity is the truth, the conceptual account of truth must include an expression of the antithesis to objectivity, a mark of the fork in the road where the way swings off; that expression will serve at the same time to indicate the tension of the subjective inwardness. Here is such a definition of truth: the truth is an objective uncertainty held fast in an appropriation process of the most passionate inwardness, the highest truth attainable for an existing individual.

Men would never be superstitious, if they could govern all their circumstances by set rules, or if they were always favored by fortune: but being frequently driven into straits where rules are useless, and being often kept fluctuating pitiably between hope and fear by the uncertainty of fortune’s greedily coveted favors, they are consequently, for the most part, very prone to credulity.

Congreve, William Congreve - Uncertainty and expectation are the joys of life. Security is an insipid thing and the overtaking and possessing of a wish, discovers the folly of the chase.

After the day’s struggle there is no freedom like unfettered thoughts, no sound like the music of silence. And though behind you lies a road of dust and heat and discouragement, and before you the challenge and uncertainty of untried paths, in this brief hour you are master of all highways, and the universe nestles in your soul.

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

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.

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.

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.

If life were eternal all interest and anticipation would vanish. It is uncertainty which lends its fascination.

Demanding security and certainty prevents peace of mind. No human has the omniscience to foresee everything. Always realize the unexpected can occur. Plan as much as is appropriate, but realize that regardless of how much you plan there will always be difficulties that you had previously not imagined. By expecting there will always be unexpected occurrences and accepting them, you will have much greater peace of mind than if you have unrealistic expectations of complete control. A person would be making a big mistake if he felt that the way to peace of mind is to obtain complete security from all risks... Uncertainty is inevitable... The demand for success is detrimental to peace of mind... Keep your focus on trying to accomplish with the best of your ability.

The future is uncertain... but this uncertainty is at the very heart of human creativity.

The Principle of Uncertainty is a bad name. In science or outside of it we are not uncertain; our knowledge is merely confined, within a certain tolerance. We should call it the Principle of Tolerance.

In uncertainty I am certain that underneath their topmost layers of frailty men want to be good and want to be loved. Indeed, most of their vices are attempted shortcuts to love. When a man comes to die, no matter what his talents and influence and genius, if he dies unloved his life must be a failure to him and his dying a cold horror. It seems to me that if you or I must choose between two courses of thought or action, we should remember our dying and try so to live that our death brings no pleasure to the world.

Although our intellect always longs for clarity and certainty, our nature often finds uncertainty fascinating.
