“Of all of the many mysteries of modern astronomy, none is more vexing than the nature of dark matter… This dark matter has eluded every effort by astronomers and physicists to bring it out of the shadows. A handful of us suspect that it might not really exist, and others are beginning to consider this possibility seriously.”

Context: Ultimately what we really are matters more than what other people think of us. One has to face the modern world with its good as well as its bad and it is better on the whole, I think, that we give even licence than suppress the normal flow of opinion. That is the democratic method. But having laid that down, still I would beg to say that there is a limit to the licence that one can allow, more so in times of great peril to the State.

The Principles of Success in Literature (1865)
Context: Every one who has seriously investigated a novel question, who has really interrogated Nature with a view to a distinct answer, will bear me out in saying that it requires intense and sustained effort of imagination. The relations of sequence among the phenomena must be seen; they are hidden; they can only be seen mentally; a thousand suggestions rise before the mind, but they are recognised as old suggestions, or as inadequate to reveal what is sought; the experiments by which the problem may be solved have to be imagined; and to imagine a good experiment is as difficult as to invent a good fable, for we must have distinctly present — clear mental vision — the known qualities and relations of all the objects, and must see what will be the effect of introducing some new qualifying agent. If any one thinks this is easy, let him try it: the trial will teach him a lesson respecting the methods of intellectual activity not without its use.
