“The rational soul in a certain manner possesses the excellence of infinity and eternity. If this were not the case, it would never characteristically incline toward the infinite. Undoubtedly this is the reason that there are none among men who live contentedly on earth and are satisfied with merely temporal possessions.”

The Tragic Sense of Life (1913), X : Religion, the Mythology of the Beyond and the Apocatastasis
Context: May not the absolute and perfect eternal happiness be an eternal hope, which would die if it were realized? Is it possible to be happy without hope? And there is no place for hope once possession has been realized, for hope, desire, is killed by possession. May it not be, I say, that all souls grow without ceasing, some in a greater measure than others, but all having to pass some time through the same degree of growth, whatever that degree may be, and yet without ever arriving at the infinite, at God, to whom they continually approach? Is not eternal happiness an eternal hope, with its eternal nucleus of sorrow in order that happiness shall not be swallowed up in nothingness?

The Art of Persuasion
Context: All who say the same things do not possess them in the same manner; and hence the incomparable author of the Art of Conversation http://books.google.com/books?id=iRBEAAAAYAAJ&pg=PA452& pauses with so much care to make it understood that we must not judge of the capacity of a man by the excellence of a happy remark that we heard him make.... let us penetrate, says he, the mind from which it proceeds... it will oftenest be seen that he will be made to disavow it on the spot, and will be drawn very far from this better thought in which he does not believe, to plunge himself into another, quite base and ridiculous.

The Other World (1657)
Context: As God has made the soul immortal, he has made the universe infinite, if it is true that eternity is nothing other than unlimited duration and infinity is space without limits. Suppose the universe were not infinite: God himself would be finite, because he could not be where there is nothing, and he could not increase the size of the universe without adding to his own size and come to be where he had not been before.
