Nietzsche, the Madman, and Modernity's Void

The collapse of the Aristotelian order created a void that later thinkers tried to fill by reaffirming God’s place and human dignity. The Scientific Revolution disrupted the Church and university system built on Aristotle, beginning with Copernicus’s 1542 challenge to geocentrism. Newton’s 1687 Principia mathematica completed the Copernican shift by introducing laws of motion and universal gravitation. Harvey’s 1628 work demonstrated blood circulation, contradicting the idea that blood is produced in the liver and consumed at the body’s periphery. Galileo’s 1632 findings showed uniform acceleration of falling objects regardless of mass. Harvey and Galileo emphasized experiment and observation over inherited authorities, and Nietzsche later declared the death of God, treating overcoming nihilism as necessary for cultural rebirth and future human flourishing.

"The Scientific Revolution disrupted the centuries-old Aristotelian system of the Church and universities. It all began in 1542, when the Pole Nicolaus Copernicus published On the Revolutions of the Heavenly Spheres. This worked challenged the geocentric system of Aristotle and Ptolemy in which the Earth-and, more importantly, man-stood proud and unmoving at the centre of the universe."

"It is arguably Newton who completed the Copernican Revolution, and put the nail in the coffin of the Aristotelian system, with the publication, in 1687, of his Principia mathematica. In this work, which is deemed impenetrable, he introduced his three laws of motion along with the Law of Universal Gravitation. In the mid-1660s, Newton kept a notebook with the title, Certain Philosophical Questions."

"Also contradicting the Aristotelian worldview were William Harvey's demonstration of the circulation of blood, published in his De motu cordis of 1628, and Galileo's discovery that falling objects undergo uniform acceleration irrespective of their mass, published in his Dialogue Concerning the Two Chief World Systems (i.e. the Ptolemaic and the Copernican) of 1632. Aristotle had held that heavier objects fall faster, and that blood is constantly produced in the liver and consumed in the body's periphery."

"More radically, both Harvey and Galileo privileged experiment and observation over the authority of Aristotle, Ptolemy, Galen, and the Bible. Only a decad"
