This is the subject of my teachings, and I go on describing all the different causes the movement of the stars across the Universe might spring from. Among these hypotheses, only one must be the right explanation, but which one deserves the crown is still beyond the grasp of those who move at an honest pace through the path to knowledge.

As for the quote from the poem On the Nature of Things by Lucretius, an early example of scientific divulgation, I’ve crafted a translation that sacrifices adherence to the original hexameters and gives up on metric, in favor of the inner meaning that I think these verses bear. The original hexameters in Latin are the following ones:

… id doceo, plurisque sequor disponere causas,
motibus astrorum quae possint esse per omne;
e quibus una tamen sit et hic quoque causa necessest,
quae vegeat motum signis; sed quae sit earum
praecipere haudquaquam est pedetemptim progredientis.

Titus Lucretius Carus, De Rerum Natura, V 529-533

The reader may have recognized some similarities with ideas promoted by natural philosophers who were born after Galileo had started the scientific revolution, about sixteen centuries apart from the end of Lucretius’ life. Besides the obvious “Hypotheses non fingo” by which Newton admitted that even though his mathematical model described so well the movement of planets, he had no idea of the cause of gravity; besides that, we can also mention Chamberlin’s “Method of Multiple Working Hypotheses” that seems to follow the footprints of these few lines from the fifth book of De Rerum Natura. Lines in which almost a presage of the convergence of a Baconian series can perhaps be acknowledged; a prophecy that has traveled through twenty centuries to teach us what we have painfully learned again during this vertiginous hiatus and that we often forget about.


Non ho la mia età, lo sai. Ma non perché abbia vissuto meno degli anni sui documenti: la verità è che gli anni li ho tutti, tutti quelli della Storia. Vestivo la musica con le ossa cave, nei Balcani: intagliavo le asole ai femori d’orso, cercando le note che vibrano dentro le note, d’istinto pesando … Continue reading Asmara

Anatomy of a conflict

Putin recognizes two new independent republics on the east border of Ukraine so that he can enter Ukraine, without formally entering it (February 23rd, 2022). In this satiric illustration, Putin is stretching Ukraine’s borders with its own hands, making room for two new independent republics which are created with the only aim of allowing the … Continue reading Anatomy of a conflict

Ratio between two Random Variables: the case of the Beta Distribution

We have here a paradox: what theory is it that is not correct unless it leaves open the possibility that it may be incorrect? Answer: the theory of probability. P.W. Bridgman, The Nature of the Physical Theory While reasoning on one of the biological problems I have been spending most of my time on, I … Continue reading Ratio between two Random Variables: the case of the Beta Distribution
