Can you imagine a world without books? I can't. Nor do I want to. What would our world be without books, magazines, any kind of printed material? I shudder to think of it.
None of these would be possible without Johannes Gutenberg, who invented movable type somewhere around 1430. From movable type came the printing press, also invented by Gutenberg. This eventually led to the mass production of the Bible, putting the holy book into the hands of people who would have never had access to it otherwise.
Gutenberg's vision brought learning and enlightenment to a world that had literally been in the Dark Ages, an era of unimaginable cruelty, ignorance, and intolerance.
So, for today, I am grateful for a visionary man.
