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.
