Tesla

 In 1900, Nikola Tesla [the inventor of the AC current and radio] wrote:  "We are all one.  Metaphysical proofs are, however, not the only ones which we are able to bring forth in support of this idea.  Science, too, recognizes this connectedness of separate individuals, though not quite in the same sense as it admits that the suns, planets, and moons of a constellation are one body, and there can be no doubt that it will be experimentally confirmed in times to come, when our means and methods for investigating psychical and other states and phenomena shall have been brought to great perfection."  We now have greater understanding of how connected we, as humans, truly are to each other.  How is it that a species so closely connected at a molecular level can have so much conflict within itself?
