How universal is gratefulness?

Gratefulness – the simple response of our heart to this life in all its fullness – goes beyond boundaries of creed, age, vocation, gender, and nation.   J. Robert Moskin, former foreign editor for Look magazine and senior editor for Collier's, writes that “thanksgiving comes to us out of the prehistoric dimness, universal to all ages and all faiths. At whatever straws we must grasp, there is always a time for gratitude and new beginnings.”  The following diverse array of quotes reflects this universality as a representative sample.  A comprehensive list, we’re happy to say, would take years to compile.
