Meaning of "manussa"

The Pali and Sanskrit languages use the word "manussa" or "manusya" when referring to humans. It is a very meaningful word. Incidentally, the English word "Man" is derived from the Sanskrit word "manu" meaning "to think".  

 
Humans are the only living beings who can cultivate and develop the mind to its maximum level. Such a living being is called manussa (human). The word "man" is also derived from the word mana meaning mind. Thus one who has a mind to think is called man.  

With his superior intelligence, man has only to direct and channel his desires and he can make his life to be what he chooses. (Of course when we refer to "man", here we are thinking of all humans, men and women. There is no need to think that women are in any way inferior to men either intellectually or spiritually or morally).  

 
The Chinese definition of human is "one with a heart disposed to kindness". In the human heart, there must be sympathy and honesty. If these two qualities are absent, then one is not regarded as a real human being.  

Western philosophers define "humans" as those who can use their sense of reasoning. Humans are the only beings who are rational in their behaviour. Other living beings use only their instinct to ensure their survival, pleasure and protection. When the mind is cultivated by abstaining from evil thoughts and developing the great virtues, one can gain this tranquillity which leads to the purity of the mind.
