Nations and peoples exchange all the ideas and their long-term collaboration in the fields of science and art. But there is also a main reason, which implies many wars; Is the economic factor that becomes "social and global". I believe that the ideal world- alas!- moves further and further away since personalized and individual selfishness is spreading, and for this reason only wisdom and art as a whole can save humanity because makes everyone participate and rational. Yes, the unity in the humanistic knowledge and the brotherhood , could lead to an ideal world, the collaborative wisdom between peoples is a fact, because we will no longer speak of nations but of international world people where interests, goals and objectives are common. This may be a hypothetical thought that sees the world through the soul.
