Almost all of this detailing has been done by those who would identify themselves as "secular humanists": those committed to Enlightenment ideals like, inter alia, reason, science, naturalism, democracy, equality, and the possibility of progress in ethics, politics, and happiness through those means.
The Enlightenment has both a light and dark side. Marxism, socialism, communism, the French Revolution, Walden Two, and Brave New World are all as much children of the Enlightenment as are Republican government, political liberty, civil rights, and equality under the law.
One of the primary problems of the 20th century has been, indeed, that reason has become, not just an ideal, as opposed to an intellectual tool useful for certain kinds of work and limited or useless for others, but a totem, and reason, elevated to the level of a totem, gave us the mass graves, gulags, and genocide of the last century, just as, in its proper sphere, it gave us our modern living standards, our prosperity, and the wonders of our technology.
"naturalism" is a philosophy that makes metaphysical assumptions about the universe not subject to empirical verification or falsifiability, and hence, according to Tal's own implications here, should have been left behind with geocentric solar system, or never conceived at all, within the context of Enlightenment rationalism (which was also a bastard offspring of the Enlightenment, not a necessary aspect of the Enlightenment itself).
The rest is rather laughable, as progress in ethics, politics, and happiness though purely human means is probably the greatest non-event of human history. Indeed, the 20th century, the century that saw more blood, more death, more war, and more contrived, engineered, and willfully constructed human misery in the history of all mankind, most of it in the name of scientific social control, reason, equality, and human salvation through rationality, planning, social, cultural, and behavioral control, and material abundance, has been the antithesis of the scientistic and naturalistic conceits and hubris that lie at the core of what is termed "Secular Humanism".
From the Enlightenment, we have Jefferson, Jay, Madison, and Franklin. We also have Hegel, Nietzsche, Comte, Satre and Marx. We have William F. Buckley, and Peter Singer. We have America, and have had the U.S.S.R. Communist China, Cuba, and Nazi Germany. We've had Susan B. Anthony and Margaret Sanger. The Enlightenment gave us Freud, Watson, and Skinner, as well as Maslow. We have embryonic stem cell research (as scientific dead end, but live political issue) and other forms of such research (scientifically valuable, but politically inert).
The Enlightenment gave us the some forty million of the unborn slaughtered since 1973 so we could the better enjoy the fruits and possibilities of its personal liberties and material prosperity, as well as the means to accomplish it.
This is the Pandora's Box of the Enlightenment. much more complex than the simplistic liberation from the darkness of superstition and religion story we've all been told by the secularist mandarins of our intellectual institutions.
