From Comenius' ‘Via Lucis’ (1641 AD):
‘According to the Creator’s objectives, the world is nothing more than a foreplay to eternity, as it were a primary school where we are sent before we can be promoted to the heavenly college. And that is why he has lavishly equipped his school with his books.
Because since it is our task here to learn, and learning without books or oral instruction is not possible, he teaches us, in the meantime with the help of his books, since the latter is reserved for eternity. He has given us three books, all three of which are copies of his eternity, that means, of himself, as it were as from an original.
The first and largest book of God is the visible world, written in as many letters as there are creatures of God. The second book is man himself, created in God’s image. To him, inspired by the breath of divine life, that is, by the reasonable spirit, made according to the measure of all things.
However, God has handed man a third book, as it were an explanation of the outer book of the world and as a guideline for the conscience, which is the inner book: the Holy Scripture, in which he sheds light on some more hidden aspects of both other books, and teaches the true purpose and use of all things.
In this threefold book of God everything is included that we humans must know or do not know, and clearly explained for the benefit of all.’
