“Every object that we perceive appears in innumerable aspects. The concept of the object is the invariant of all these aspects.”
The close of his Nobel lecture: "The Statistical Interpretations of Quantum Mechanics" (11 December 1954) http://nobelprize.org/nobel_prizes/physics/laureates/1954/born-lecture.html
Context: Can we call something with which the concepts of position and motion cannot be associated in the usual way, a thing, or a particle? And if not, what is the reality which our theory has been invented to describe?
The answer to this is no longer physics, but philosophy. … Here I will only say that I am emphatically in favour of the retention of the particle idea. Naturally, it is necessary to redefine what is meant. For this, well-developed concepts are available which appear in mathematics under the name of invariants in transformations. Every object that we perceive appears in innumerable aspects. The concept of the object is the invariant of all these aspects. From this point of view, the present universally used system of concepts in which particles and waves appear simultaneously, can be completely justified. The latest research on nuclei and elementary particles has led us, however, to limits beyond which this system of concepts itself does not appear to suffice. The lesson to be learned from what I have told of the origin of quantum mechanics is that probable refinements of mathematical methods will not suffice to produce a satisfactory theory, but that somewhere in our doctrine is hidden a concept, unjustified by experience, which we must eliminate to open up the road.

Context: The objective world is only “material”: it’s there, but it could be there in a great many different forms and aspects... Even here there [are] still possibilities: it can’t be just anything. But perhaps extracting a finite schema from the variety of mythologies, literatures, or religions might contribute something to the understanding of what some of these possibilities could be. The individual can’t create his own world, except in art or fantasy: society can only create a myth of concern. What fun if one could get just a peep at what some of the other worlds are that a new humanity could create–no, live in. (p. 287-8)
At the other extreme is a set of parts that are completely unrelated: that is, a change in each part depends only on that part alone. The variation in the set is the physical sum of the variations of the parts. Such behavior is called independent or physical summativity.

“The whole aspect of the universe changes with this new conception.”
Kropotkin here may be refering to the French scientist Joseph Fourier, and not the French social philosopher Charles Fourier
Anarchism: Its Philosophy and Ideal (1896)
Context: The whole aspect of the universe changes with this new conception. The idea of force governing the world, of pre-established law, preconceived harmony, disappears to make room for the harmony that Fourier had caught a glimpse of: the one which results from the disorderly and incoherent movements of numberless hosts of matter, each of which goes its own way and all of which hold each other in equilibrium.
