That man who before he comes into power has no friends, or who coming into power is obliged to desert his friends, or who losing it has no friends to sympathize with him

Context

“It is no mean security for a proper use of power, that a man has shewn by the general tenor of his actions, that the affection,the good opinion, the confidence, of his fellow citizens have been among the principal objects of his life; and that he has owed none of the gradations of his power or fortune to a settled contempt, or occasional forfeiture of their esteem. That man who before he comes into power has no friends, or who coming into power is obliged to desert his friends, or who losing it has no friends to sympathize with him; he who has no sway among any part of the landed or commercial interest, but whose whole importance has begun with his office, and is sure to end with it; is a person who ought never to be suffered by a controuling Parliament to continue in any of those situations which confer the lead and direction of all our public affairs;” source
