The wise can learn from the foolish as the foolish can learn from the wise

A wise man was once foolish

Not all philosophy's are wise but than again every philosophy is thought by man and every man was once foolish for man is not born wise but rather learns to becomes wise

Ignorance causes all foolish thoughts and actions

You can be wise in certain things but to be consider a wise person you have to be wise in all

All that is humane concept and theory is deep confusion
