Man's domain both in the sphere of his knowledge, information and outlook and in the sphere of his desires, wants and inclinations is very vast and lofty. Man's knowledge passes from the exterior of the things to their inner reality, their mutual relations and to the laws governing them. His knowledge does not remain confined to any particular place or time. It surpasses all such limitations.
On the one hand, his knowledge extends to the events which took place before his birth, and on the other, it extends to other planets and stars. He gets acquainted with his past as Well as his future. He discovers his own history and that of the World, which is the history of the earth, the sky, the mountains, the rivers, the plants and the living organisms. Not only he thinks of the remote future, but also applies his thought to infinities and eternities, some of which he recognizes. Man goes a step further from identifying the individuality and particularity, and with a view to control nature, discovers universal rules and general truths prevailing in the world.
From the viewpoint of his ambitions and aspirations also man holds an outstanding position, for he is an aspiring, high thinking and idealistic being. He seeks objectives which are not of material and profitable nature; objectives which are in the interest of entire humanity and not confined to himself and his family or to any particular region or to a particular period of time.
Man is so idealistic that he often gives more importance to his creed and ideology than to any other value. He may consider service to others to be of more consequence than his own welfare, and may regard a thorn stuck into the foot of someone else as being stuck into his own foot or even his own eye. He feels sympathy with others and shares their joy and grief. Man becomes so devoted to his creed and sacred ideology that he easily sacrifices his life for them.
The human aspect of the human culture which is considered to be its true spirit is the outcome of such feelings and desires.
