When IBM’s Deep Blue defeated world chess champion Garry Kasparov in May 1997, it established that computers could outperform human experts in an activity long associated with superior intelligence. Yet Deep Blue’s achievement rested largely upon a familiar principle: calculating enormous numbers of possibilities and selecting the most promising result. Nineteen years later, Demis Hassabi’s DeepMind demonstrated something different. During its March 2016 match against Go champion Lee Sedol, AlphaGo played a move so unconventional that professional observers initially struggled to understand it. Move 37 in Game 2 raised a question that remains central to artificial intelligence: Can a machine do more than calculate? Can it develop something resembling intuition?
Traditional astrology provides a useful framework for approaching this distinction through the relationship between Mercury and the Moon. Mercury signifies rational intelligence, calculation, language, and the manipulation of information. The Moon signifies perception, instinct, responsiveness, and the intuitive apprehension of circumstances. These faculties are not necessarily opposed. Indeed, certain planetary configurations may describe their integration, producing an intellectual style in which the essential structure of a problem is grasped before its constituent parts have been subjected to systematic analysis.
Three figures from my recent Aquarius Tech Bros series illustrate this possibility: Elon Musk, with Mercury/Cancer in mutual reception with Moon/Virgo, and Jeff Bezos and Dario Amodei, both with Mercury/Capricorn retrograde. Despite their different professional accomplishments, all three display an inclination to recognize broad structural relationships before undertaking the detailed work required to realize their ideas.
Mercury/Capricorn versus Mercury/Cancer
Mercury/Capricorn direct signifies disciplined, methodical reasoning. Intelligence proceeds sequentially, assembling individual observations into increasingly elaborate structures. The process resembles a PowerPoint presentation organized into bullet points: each conclusion follows from the preceding one, and progress is measured by moving systematically through the argument.
The weakness of this approach is that it may overlook relationships falling between established categories. Capricorn follows the steps but can skip the cracks.
Mercury/Cancer operates differently. Cancer is a water sign, and water fills every available opening. Rather than dissecting a problem into discrete components, Cancerian intelligence apprehends the whole, including relationships that may not be apparent through sequential analysis. The essential structure of the problem can emerge virtually simultaneously, before the individual steps required to explain it have been identified.
This is the difference between constructing a picture from its individual pieces and recognizing the picture before determining how those pieces fit together.
Under the retrograde/opposite-sign principle employed in my research, Mercury/Capricorn retrograde can acquire some of the intellectual qualities of Mercury/Cancer. Retrogradation reverses the normal direction of reasoning. Instead of proceeding from isolated facts toward a general conclusion, the individual begins with a comprehensive insight and subsequently reconstructs the analytical steps necessary to demonstrate it.
The intuitive apprehension comes first; the rational explanation follows.
This does not imply that Mercury retrograde abandons reason. Rather, reason becomes the instrument through which an initially holistic understanding is implemented.
Henri Bergson: The Moon as Intuition
The philosophical foundation for this distinction can be found in Henri Bergson (1859–1941), whose work I examined in a previous House of Wisdom article.
Bergson argued that conventional analytical intelligence cannot fully comprehend reality because it substitutes fixed observations and abstract categories for the continuous movement of existence. To understand something through analysis is to observe it from the outside, constructing a representation from a succession of separate viewpoints.
True intuition requires something different. Rather than observing an object through a series of static measurements, the observer must enter into its movement and apprehend the process from within.
Consider a melody. Its meaning cannot be recovered simply by examining each note separately. The melody exists through the continuous relationship among its notes, including their movement through time. To understand it, one must apprehend the musical whole rather than merely accumulate individual observations.
Bergson developed this distinction in An Introduction to Metaphysics (1903), contrasting analysis with intuition as fundamentally different approaches to knowledge.
His horoscope provides a corresponding astrological structure. The Moon in Cancer, in its own domicile, applies to Jupiter exalted in Cancer, which I have identified as victor of his horoscope. Lunar perception and intuition are consequently enlarged into a comprehensive philosophical system. Bergson’s concept of duration, or reality experienced as continuous movement rather than a succession of isolated moments, offers a particularly clear expression of the Moon’s intuitive nature.
Bergson is therefore an appropriate exemplar of lunar intuition operating without the necessity of reducing experience to a sequence of discrete analytical operations.
This distinction predates electronic computing. Bergson was identifying limitations of mechanical and analytical reasoning decades before computers would demonstrate just how powerful those methods could become.
From Deep Blue to AlphaGo
The development of artificial intelligence provides a practical setting in which to reconsider Bergson’s argument.
IBM’s Deep Blue defeated Kasparov in a six-game match in May 1997. The machine combined extensive chess knowledge with the capacity to evaluate approximately 200 million positions per second. Its search methods allowed it to compare enormous numbers of possible continuations and select moves according to programmed evaluation criteria.
Astrologically, this is an expression of Mercury’s rational powers: calculation, comparison, classification, and the systematic manipulation of information. Deep Blue did not need to experience the movement of the game as a human player might. Its computational capacity was sufficient to defeat the reigning world champion.
AlphaGo represented a different development.
On 10-Mar-2016, during Game 2 of its match against Lee Sedol, AlphaGo played Move 37, placing a stone in a position that professional players considered highly unconventional. DeepMind subsequently reported that its model estimated a human professional would select the move with a probability of approximately one in ten thousand.
Yet the move proved strategically valuable. AlphaGo had identified a possibility that lay outside established human expectations.
The distinction between the two systems was not simply greater computing power. AlphaGo combined tree-search methods with deep neural networks trained to recognize promising moves and evaluate the overall position. Reinforcement learning allowed the system to improve through experience, discovering strategies that did not depend entirely upon reproducing the established judgments of human experts.
The progression from Deep Blue to AlphaGo suggests that machines can develop increasingly sophisticated approximations of intuitive judgment. But can astrology identify a comparable relationship between rational and intuitive intelligence in human beings? The horoscopes of Jeff Bezos, Dario Amodei, and Elon Musk offer three examples, each illustrating a different way in which Mercury’s analytical faculties may become integrated with the Moon’s intuitive perception.
