What is not taken into account is the motivation of activity. Take for instance a man driven to incessant work by a sense of deep insecurity and loneliness; or another one driven by ambition, or greed for money. In all these cases the person is the slave of a passion, and his activity is in reality a "passivity" because he is driven; he is the sufferer, not the "actor." On the other hand, a man sitting quiet and contemplating, with no purpose or aim except that of experiencing himself and his oneness with the world, is considered to be "passive," because he is not "doing" anything.
Spinoza arrives at the statement that virtue and power are one and the same. Envy, jealousy, ambition, any kind of greed are passions; love is an action, the practice of a human power, which can be practised only in freedom and never as the result of a compulsion.
Giving is more joyous because in the act of giving lies the expression of my aliveness.
What does one person give to another? He gives of himself, of the most precious he has, he gives of his life. This does not necessarily mean that he sacrifices his life for the other--but that he gives him of that which is alive in him; he gives him of his joy, of his interest, of his understanding, of his knowledge, of his humor, of his sadness- of all expressions and manifestations of that which is alive in him. In thus giving of his life, he enriches the other person, he enhances the other's sense of aliveness by enhancing his own sense of aliveness. He does not give in order to receive; giving is in itself exquisite joy.
It presupposes the attainment of a predominantly productive orientation; in this orientation the person has overcome dependency, narcissistic omnipotence, the wish to exploit others, or to hoard, and has acquired faith in his own human powers, courage to rely on his powers in the attainment of his goals.
