Spinoza's human nature is inseparable from the anthropology of social life in his philosophy, Nor about his possible ranks of knowledge, Our practical life belongs to our mental life. But man himself is a one of Conditions "God" or nature as it is all, And it is governed in life by emotional elements, most notably (desire) As a direct expression of a persons tendency to preserve his existence, being aware of this tendency, Therefore, it was necessary for the person to strive to overcome his emotions in order for this to confirm the social meanings in himself, That is the basis of virtue. True happiness, which is the desired goal of human life, does not lie in the pleasure of the body and the tendency to save survival, But in doing good. The "Conatus" is associated with this tendency, The power of being expressed necessarily within all individual beings represents the Infinity power of "God". If the wisdom of a free man is to meditate not in death but in life, Salvation will only occur for those who apply this rule in life: That is, for those who obey "God", Whereas those who live under the pleasure of perishing perish" And who imagined the destruction of what he hated was happy". This is the case of a person at Spinoza,and This is the nature of the good and practical life he must live.
