The use of language as a means of communication is so ancient that its origins are not known. The earliest forms of language may have evolved from the imitation of sounds in nature, instinctive cries or verbal sounds that accompanied body movements. A work of literature is a creative, universal form of expression that addresses the emotional, spiritual, or intellectual concerns of humanity. Literature can be experienced privately, for example when we read a poem in the quiet of our own room, or publicly, such as when we attend a play. Literature is often thought of as a written form of expression, but there are many strong oral traditions in both aboriginal and modern societies.
Philosophy deals with the most general questions of life, existence, and reality.
Philosophy is not a science as its questions can't be answered by experiments. Its concerned with rigourous conceptual analysis and reasoning, and critical examination of the grounds for fundamental beliefs. It seeks the most general, abstract, and ultimate character of the world in which we find ourselves. There are several branches of learning that deal with the origins and activities of human groups. The size of such groups ranges from the family, tribe, and nation up to the relationships between nations.
