We can’t form our children on our own concepts; we must take them and love them as God gives them to us.
The existing scientific concepts cover always only a very limited part of reality, and the other part that has not yet been understood is infinite.
The conception and its existence are two sides, distinct yet united, like soul and body. The body is the same life as the soul, and yet the two can be named independently. A soul without a body would not be a living thing, and vice versa. Thus the visible existence of the conception is its body, just as the body obeys the soul which produced it.
Any concepts or words which have been formed in the past through the interplay between the world and ourselves are not really sharply defined with respect to their meaning: that is to say, we do not know exactly how far they will help us in finding our way in the world.
