“Learned we may be with another man's learning: we can only be wise with wisdom of our own.”

“It takes a wise man to learn wisdom from a wise woman!”

“Only a fool learns from his own mistakes. The wise man learns from the mistakes of others.”

“God hath thus ordered it, that we may learn to bear one another’s burdens; for no man is without fault, no man without his burden, no man sufficient of himself, no man wise enough of himself; but we ought to bear with one another, comfort one another, help, instruct, and admonish one another.”

“Wise is the one who learns from another´s mistakes. Less wise is the one who learns only from his own mistakes. The fool keeps making the same mistakes again and again and never learns from them.”

“Only for you, children of doctrine & learning, have we written this work. Examine this book, ponder the meaning we have dispersed in various places & gathered again; what we have concealed in one place we have disclosed in another, that it may be understood by your wisdom.”
