All the evolution we know of proceeds from the vague to the definite.
Interpretation
Evolution involves moving from unclear ideas to clear concepts.
This quote by Charles Sanders Peirce emphasizes that the process of evolution, whether in thought, ideas, or life itself, transitions from ambiguity and uncertainty towards clarity and definition. It suggests that understanding and advancement require time, experience, and a gradual refining of thoughts and ideas as they evolve into more concrete forms.
In practice
During a presentation on innovation, you might use this quote to illustrate how ideas develop over time.
The final upshot of thinking is the exercise of volition, and of this thought no longer forms a part; but belief is only a stadium of mental action, an effect upon our nature due to thought, which will influence future thinking.
Notwithstanding all that has been discovered since Newton's time, his saying that we are little children picking up pretty pebbles on the beach while the whole ocean lies before us unexplored remains substantially as true as ever, and will do so though we shovel up the pebbles by steam shovels and carry them off in carloads.
My language is the sum total of myself.
The third class consists of men to whom nothing seems great but reason. If force interests them, it is not in its exertion, but in that it has a reason and a law. For men of the first class, nature is a picture; for men of the second class, it is an opportunity; for men of the third class, it is a cosmos, so admirable, that to penetrate to its ways seems to them the only thing that makes life worth living. These are the men whom we see possessed by a passion to learn.
A quality is something capable of being completely embodied. A law never can be embodied in its character as a law except by determining a habit. A quality is how something may or might have been. A law is how an endless future must continue to be.
In all the works on pedagogy that ever I read β and they have been many, big, and heavy β I don't remember that any one has advocated a system of teaching by practical jokes, mostly cruel. That, however, describes the method of our great teacher, Experience.
We have to face the unpleasant as well as the affirmative side of the human story, including our own story as a nation, our own stories of our peoples. We have got to have the ugly facts in order to protect us from the official view of reality. Otherwise, we are squeezed empty and filled with what other people want us to think and feel and experience.
Golden fetters are no less galling to a self-respecting man that iron ones; the sting lies in the fetters, not in the metal.
In life our first job is this, to divide and distinguish things into two categories: externals I cannot control, but the choices I make with regard to them I do control. Where will I find good and bad? In me, in my choices.
Dreams and restless thoughts came flowing to him from the river, from the twinkling stars at night, from the sun's melting rays. Dreams and a restlessness of the soul came to him.
We are all potentially such sick men. The sanest and best of us are of one clay with lunatics and prison-inmates. And whenever we feel this, such a sense of the vanity of our voluntary career comes over us, that all our morality appears but as a plaster hiding a sore it can never cure, and all our well-doing as the hollowest substitute for that well-being that our lives ought to be grounded in, but alas! are not.
The 'Grace of Kings' isn't a narrative about a return to some golden age, to a lost status quo ante. It portrays a dynamic world in transition, where the redistribution of power is messy, morally ambivalent, and only lurches toward more justice.
