Negativity is not intelligent. It is always of the ego. The ego may be clever, but it is not intelligent. Cleverness pursues its own little aims. Intelligence sees the larger whole in which all things are connected. Cleverness is motivated by self-interest, and it is extremely short-sighted. Most politicians and businesspeople are clever. Very few are intelligent. Whatever is attained through cleverness is short-lived and always turns out to be eventually self-defeating. Cleverness divides; intelligence includes.
