Human Species Quotes

By making our defenseless planet the ultimate beneficiary of our economic activity, we align our values with a different set of motivations. When we begin to see life as an interdependent mesh, we place the survival of the human species on equal footing with our economic interests and ourselves.

Said Elias Dawlabani

The difficulty is that, so long as unreason prevails, a solution of our troubles can only be reached by chance; for while reason, being impersonal, makes universal co-operation possible, unreason, since it represents private passions, makes strife inevitable. It is for this reason that rationality, in the sense of an appeal to a universal and impersonal standard of truth, is of supreme importance to the well-being of the human species.

Bertrand Russell

Our probable ancestors, Homo erectus and Homo habilis -now extinct- are classified as of the same genus (Homo) but of different species, although no one (at least lately) has attempted the appropriate experiments to see if crosses of them with us would produce fertile offspring.

I had written the sentence, 'You mustn't think that the evolution that gave rise to us was the only evolutionary possibility on this planet. . . . that cultural developments could be shaped through the mediation of another animal species. If the biological conditions were favorable, some civilization not inferior to our own could arise in the depths of the sea. . . . Would it do the same stupid things mankind has done? Would it invite the same historical calamities? What would we say if some animal other than man declared that its education and its numbers gave it the sole right to occupy the entire world and hold sway over all creation?

While we maintain the unity of the human species, we at the same time repel the depressing assumption of superior and inferior races of men. There are nations more susceptible of cultivation, more highly civilized, more ennobled by mental cultivation than others—but none in themselves nobler than others.

Alexander von Humboldt

Consider the species known as man. We lie, we cheat, we want what others have and take it; we make war upon each other and the earth; we harvest lives in multitude. We have mortgaged the planet and spent the cash on trifles.
