There was a previous, far inferior version of this revision, don't get confused by it.
This is my final version, with the following changes.
- removed lots of false quotes in case their source was not ancient, they could not be found or were misleading in context
- removed lots of boring quotes
- added lots of new quotes (500 characters max., some may still be too long)
- all quotes include their source
- many quotes reworded and translated into modern English
- many quotes improved by providing historical context
- removed useless string "Quote of the Day"
