CAUSES OF HUMAN MISERY
6. Many are surprised that on Earth there is so much badness, so many crude passions, so many miseries and every kind of sickness. From this, they conclude, the human species is a very miserable one. This judgement comes from the very narrow point of view of those who emit it, which gives a false idea of the whole.
We must consider, however, that in actual fact, the entirety of humanity is not all on Earth, but only a small fraction of the total. In effect, the human species covers all those endowed with reason who inhabit the innumerable orbs of the Universe. What then is the mere population of the Earth when compared with the total population of all the worlds? Much less than that of a very small village when compared with a great empire.
The material and moral situation of terrestrial humanity is not surprising, when we take into consideration the destiny of the Earth and the nature of its inhabitants. 7. It would be a great mistake to judge all the inhabitants of a city by those who inhabit the lowest and most sordid places. In a hospital we see none but the sick and mutilated; in a prison we find gathered together all kinds of vileness, baseness and many vices; in unhealthy regions the inhabitants are, for the most part, pale, puny and sickly.
Well then, picture the Earth as a combination of a suburb, a hospital, and an unhealthy place, because it is all of these put together. Then it can be understood why afflictions outweigh pleasures, for we do not send those who are healthy to hospital, nor do we throw those who have practiced no wrong into houses of correction; neither can hospitals nor houses of correction be places of delight. So in the same way that the total population of a city is not to be found in us hospitals and prisons, we do not find the total population of humanity here on Earth. Just as the sick leave hospital when they are cured and those who have served their term leave prison, when Man is cured of all his moral infirmities he will also leave the Earth environment to go to happier worlds.
