Thus, here I want to note the thought of three men who, while very different thinkers, helped shape the way we imagine human nature today: Friedrich Nietzsche, Karl Marx, and Charles Darwin. All three in their different ways provided conceptual justification for rejecting the notion of human nature and thus paved the way for the plausibility of the idea that human beings are plastic creatures with no fixed identity founded on an intrinsic and ineradicable essence.
