“Universal access to human knowledge is in our grasp, for the first time in the history of the world. This is not a bad thing.”

Draft for a Statement of Human Obligation (1943)
Context: There is a reality outside the world, that is to say, outside space and time, outside man's mental universe, outside any sphere whatsoever that is accessible to human faculties.
Corresponding to this reality, at the centre of the human heart, is the longing for an absolute good, a longing which is always there and is never appeased by any object in this world.
Another terrestrial manifestation of this reality lies in the absurd and insoluble contradictions which are always the terminus of human thought when it moves exclusively in this world.
Just as the reality of this world is the sole foundation of facts, so that other reality is the sole foundation of good.
That reality is the unique source of all the good that can exist in this world: that is to say, all beauty, all truth, all justice, all legitimacy, all order, and all human behaviour that is mindful of obligations.
Those minds whose attention and love are turned towards that reality are the sole intermediary through which good can descend from there and come among men.
Although it is beyond the reach of any human faculties, man has the power of turning his attention and love towards it.
Nothing can ever justify the assumption that any man, whoever he may be, has been deprived of this power.
It is a power which is only real in this world in so far as it is exercised. The sole condition for exercising it is consent.
This act of consent may be expressed, or it may not be, even tacitly; it may not be clearly conscious, although it has really taken place in the soul. Very often it is verbally expressed although it has not in fact taken place. But whether expressed or not, the one condition suffices: that it shall in fact have taken place.
To anyone who does actually consent to directing his attention and love beyond the world, towards the reality that exists outside the reach of all human faculties, it is given to succeed in doing so. In that case, sooner or later, there descends upon him a part of the good, which shines through him upon all that surrounds him.

Context: In a well worn metaphor, a parallel is drawn between the life of man and the metamorphosis of the caterpillar into the butterfly; but the comparison may be more just as well as more novel, if for its former term we take the mental progress of the race. History shows that the human mind, fed by constant accessions of knowledge, periodically grows too large for its theoretical coverings, and bursts them asunder to appear in new habiliments, as the feeding and growing grub, at intervals, casts its too narrow skin and assumes another, itself but temporary. Truly the imago state of Man seems to be terribly distant, but every moult is a step gained, and of such there have been many.

A Power Governments Cannot Suppress, p. 270.
Context: To be hopeful in bad times is not just foolishly romantic. It is based on the fact that human history is a history not only of cruelty, but also of compassion, sacrifice, courage, kindness. What we choose to emphasize in this complex history will determine our lives. If we see only the worst, it destroys our capacity to do something. If we remember those times and places — and there are so many — where people have behaved magnificently, this gives us the energy to act, and at least the possibility of sending this spinning top of a world in a different direction. And if we do act, in however small a way, we don’t have to wait for some grand utopian future. The future is an infinite succession of presents, and to live now as we think human beings should live, in defiance of all that is bad around us, is itself a marvelous victory.
