"Each time I reason, each time I try to use logic, I'm extremely pesimistic. When I use my heart, when I use my faith - and I have a stainless faith in mankind - then I become optimistic. A situation will arise that will awaken people, and we will suddenly understand that we have to join forces."

 “Each of the various creatures, willed in its own being, reflects in its own way a ray of God's infinite wisdom and goodness.

Catechism of the Catholic Church
