They’re often a bit cliché, but there are always a few forum signatures that justify their existence with something profound or at least mildly interesting. Here are some of the latter:

  • “There are no mysteries, only a lack of information.”

  • “There are no miracles, only unknown scientific facts.”

  • “The Doors of Wisdom are now open to everyone without exception.”

  • “The only way forwards is not backwards, unless you’re travelling on a circular path, which on Earth is all but inevitable, unless you’re a flat earther, in which case you’ve lost a dimension and think pizzas are the width of noodles.”

  • “Two things are infinite: the universe and human stupidity; and I’m not sure about the universe.”

  • “He who doesn’t want to see is afraid of discovering.”

Okay I admit, they were all transcribed from the same signature except for one which I blatantly made up. I’ll leave as an exercise for the reader to guess which.
