"The core of the belief in progress is that human values and goals converge in parallel with our increasing knowledge. The twentieth century shows the contrary. Human beings use the power of scientific knowledge to assert and defend the values and goals they already have. New technologies can be used to alleviate suffering and enhance freedom. They can, and will, also be used to wage war and strengthen tyranny. Science made possible the technologies that powered the industrial revolution. In the twentieth century, these technologies were used to implement state terror and genocide on an unprecedented scale. Ethics and politics do not advance in line with the growth of knowledge – not even in the long run." — John Gray from the essay ‘Joseph Conrad, Our Contemporary’ in Heresies (retirado daqui)
