Fools rush in where angels fear to tread.

Fools rush in where incumbents fear to tread.

For fools rush in where angels fear to tread

Pride is still aiming at the best houses: Men would be angels, angels would be gods. Aspiring to be gods, if angels fell; aspiring to be angels men rebel.

It is impossible for the fools to tread the path of learned ones.

Everyone gets scared at times. It's only the fools who won't admit it.
