Francis Bacon : " Of Great Place ".

The vices of authority are four:delays,corruption,roughness,and facility.For delays give easy access; keep times appointed;go through with that which is in hand;and interlace not business but of necessity.For corruption, do not only bind thine own hands or thy servants' hands from taking,but bind the hands of suitors also from offering;for integrity used doth the one;for integrity professed,and with a manifest destination of bribery,doth the other;and avoid not only the fault,but the suspicionWhoever is found variable, and changeth manifestly without manifest cause, giveth suspicion of corruption: therefore,always,when thou changest thine opinion or course, profess it plainly and declare it, together with the reason that move thee to change, and do not think to steal it. A servant or a favourite, if he be inward, and no other cause of esteem, is commonly thought but a by-way to close corruption. For roughness,it is a needless cause of discontent: severity breedeth fear,but roughness breedeth hate.Even reproofs from authority ought to be grave,and not taunting.As for facility,it is worse than bribery;for bribes come but now and then;but if importunity or idle respects lead a man,he shall never be without.As Salomen saith,To respect persons is not good; for such a man will transgress for a piece of bread.

Victor Hugo in " The Miserables "

Do not inquire the name of him who asks a shelter of you. The very man who is embarrassed by his name is the one who needs shelter.

Victor Hugo in "Les Miserables"

.  Teach those who are ignorant as many things as possible; society is culpable in that it does not afford instructions gratis; it is responsible for the night it produces.This soul is full of shadow; sin is therein committed. The guilty one is not the person who has committed the sin, but the person who has created the shadow.            

Albert Camus, in "PLAGUE", says: two and two make four but the teacher who teaches that two and two make four is not rewarded for teaching that two and two make four ; but a time comes in the history when the person who says that two and two make four is punished with death ; the question, however, is not what punishment or reward awaits the man who says that two and two make four : the question is whether two and two do make four.
