The true scientific mind is not to be tied down by its own conditions of time and space. It builds itself an observatory erected upon the border line of present, which separates the infinite past from the infinite future. From this sure post it makes its sallies even to the beginning and to the end of all things.
Whence is it that Nature does nothing in vain: and whence arises all that order and beauty which we see in the world?…does it not appear from phenomena that there is a Being incorporeal, living, intelligent, omnipresent, who in infinite space, as it were in his Sensory, sees the things themselves intimately, and thoroughly perceives them, and comprehends them wholly.
The Tyranni rule fifty worlds; they are outnumbered hundreds to one. In such a position, simple force is insufficient. Devious methods, intrigue, assassination are their specialties. The net they weave across space is a wide one, and close-meshed. I can well believe that it extends across five hundred light-years to Earth.
And what avails it that science has come to treat space and time as simply forms of thought, and the material world as hypothetical, and withal our pretension of property and even of self-hood are fading with the rest, if, at last, even our thoughts are not finalities, but the incessant flowing and ascension reach these also, and each thought which yesterday was a finality, to-day is yielding to a larger generalization?
In the great majority of mathematical text-books there is a total lack of unity in method and of systematic development of a central theme. Propositions of very diverse kinds are proved by whatever means are thought most easily intelligible, and much space is devoted to mere curiosities which in no way contribute to the main argument.
The first commandment for every good explorer is that an expedition has two points: the point of departure and the point of arrival. If your intention is to make the second theoretical point coincide with the actual point of arrival, don't think about the means — because the journey is a virtual space that finishes when it finishes, and there are as many means as there are different ways of 'finishing.' That is to say, the means are endless.
Till now it was believed that time and space existed by themselves, even if there was nothing — no Sun, no Earth, no stars — while now we know that time and space are not the vessel for the Universe, but could not exist at all if there were no contents, namely, no Sun, no Earth, and other celestial bodies.
I never could keep a promise. I do not blame myself for this weakness, because the fault must lie in my physical organization. It is likely that such a very liberal amount of space was given to the organ which enables me to make promises that the organ which should enable me to keep them was crowded out. But I grieve not. I like no half-way things. I had rather have one faculty nobly developed than two faculties of mere ordinary capacity.
The ideals that are the starting point for every revolution — America's revolution, Cuba's revolution, the liberation movements around the world — those ideals find their truest expression, I believe, in democracy. Not because American democracy is perfect, but precisely because we're not. And we — like every country — need the space that democracy gives us to change. It gives individuals the capacity to be catalysts to think in new ways, and to reimagine how our society should be, and to make them better.
