“We pity in others only those evils which we have ourselves experienced”

“By far the best proof is experience”

“All experience is an arch to build upon”

“I have lerned silence from the talkative, toleration from the intolerant, and kindness from the unkind; yet, strange, I am ungrateful to those teachers”

“Experience is the teacher of all things”

“Experience is not enough in itself - it has to be weighed, ordered and digested, and we have to draw the right conclusions from it”
