As an undergraduate student, I overloaded every semester (including summers) to indulge my burgeoning interests. It was all quite fulfilling, and I didn’t feel rushed, but there was a noticeable dearth of relevant humanities offerings. There are always “science for non-majors” courses, as there should be, but I’ve never heard of a “humanities for non-majors” or, better yet, “humanities for scientists”. Putting the history and philosophy of science into its full and rich context as one of humanity’s major driving forces would serve students well. It would not only enrich the content they’d be absorbing in science courses, but, more importantly, it would apply to their lives beyond the university walls and beyond their career pursuits. I’m going to start a list of topics that would constitute the outline for a “humanities for scientists” course. Who knows? Maybe I’ll even teach it someday! The list begins with a recent read that inspired this whole idea…
“On the Nature of Things” by Lucretius
The poet and philosopher Titus Lucretius Carus wrote “On the Nature of Things” sometime around 60 B.C.E., reintroducing the tenets of Greek Epicureanism (dating back to 300 B.C.E.) to his Roman audience. This work aims to explain through reasoning and observation the nature of everything. While it is easy to find flaws in a physical description of matter, life and the universe dating this far back, what is remarkable is how much is right, or at least on the right track. And you can’t help but be impressed by his rigorous thinking, bold anti-dogmatism, and beautiful expression of the freedom and enlightenment that derive from a reasoned worldview. Here is a sampling of the topics he covers:
- the atomic nature of matter and the resulting properties of compounds
- self-assembly and the physical laws of nature
- astronomy and life on other planets
- conception, death and decomposition
- the irrationality of religion, gods and superstition
- heredity, evolution and speciation
- the senses and perception
- psychology and behavior
- sleep and dreams
And he does all this in Latin hexameter verse. That’s right, it’s also a beautifully crafted epic poem. Where are the poets today who have a fraction of Lucretius’ scientific understanding? Where are the scientists today who can educate and persuade the masses through artful communication?
Almost by instinct now, with mind alert, I range those pathless groves where no one ever has gone before me and I come to fountains completely undefiled. I drink their waters; delight myself by gathering new flowers, fashioning out of them a kind of garland no muse before this time has ever given to crown a human being. I teach great things. I try to loose men’s spirits from the ties, tight-knotted, which religion binds around them. - Lucretius
Path to Atomism
Tracing the path of ideas leading to Lucretius’ description of the nature of matter in terms of indivisible atoms, we travel back over 4 centuries to Parmenides (520-450 BCE), a Greek philosopher who described all things as being singularly composed of a fiery aether. Matter could not be created or destroyed and there was no such thing as movement as that would require a void to move into, and void represents nothing and therefore does not exist. This form of reasoning follows from the work of Pythagoras (and the school of Pythagoreans to which most his acknowledgments should be shared), which conceived of numerical or unit-based formulations to describe the nature of things, often (and perhaps proudly) in direct opposition to experience and common sense. Next in line was Empedocles (490-430 BCE) who allowed for 4 basic elements to compose the universe: earth, water, fire and air. He even inferred recipes for various substances, e.g., bone was composed of 2 parts earth, 2 parts water and 4 parts fire. Hinting at forces like gravity, van der Waal, and electromagnetism, Empedocles perceived attractive and repulsive forces between the 4 elements, which he referred to as Love and Strife. Anaxagoras (500-428 BCE) upped the ante, suggesting that every substance has an elemental form and it composed of some small fraction of every type of element. Thus, bone would be primarily composed of bone elements in addition to elements of tree, water, blood, gold, etc. This was his way of addressing how things could be made of other things through cycles of birth, decay, and death without having to instatiate creation. Then came Democritus (460-370 BCE) who settled on an atomic model that supported the unifying, shared and diverse properties of matter. This model survived for 2000 years with little alteration. Despite the fact that Plato and Aristole didn’t much care for it, it was passed on to Epicurus (340-270 BCE) and reinvigorated by Lucretius (99-55 BCE). Chemistry text books in the late 17th century could be found referencing the shape and surface properties of indivisible atoms that gave rise to the properties of the composed substance (e.g., acidic tasting substances have sharp, unevenly shaped atoms). While these whimsically fabricated details do not hold up today, with a little imagination you can readily map these ancient descriptions of atoms to modern understanding.
Evolution of Evolutionary Thought
Anaximander (610-546 BCE) is the most ancient of the Greeks to have attempted a natural, materialistic explanation of life. He intuited that life started in the seas and that a series of environmental/climate circumstances led to its migration to land and the appearance of man. Details notwithstanding (e.g., he imagined early humans developing in the mouths of fish for protection from the primeval world), his ideas are in stark contrast to the invocation of myth and deities, and hint at a theory of speciation. Empedocles (490-430 BCE) got straight to the heart of the matter, explaining that the diversity of traits among living creatures was due to the fact that all manner of variations are tried and the strange deformed ones simply don’t survive, leaving only the well-suited creatures to propagate. Though, again, its his details that stray far the mark, literally (e.g., stray arms and eyes composing fantastical creatures). Aristotle (382-322 BCE) summarized Empedocles’ theory: “most of the parts of animals came to be by chance, having been randomly thrown together in the melee of the battle between love and strife. And when those parts were useful, the creatures lucky enough to have them survived, being organized spontaneously in a fitting way, whereas those that grew otherwise perished and continued to perish.” Darwin, in turn, referenced this passage saying: “you see here the principle of natural selection shadowed forth.” Funny thing is, Aristotle was restating Empedocles’ ideas in order to refute them. Aristotle was in favor of purpose over random chance and mechanism, as was Plato before him. What he lacked in terms of theoretical biology insight, he made up for in his practical application. Aristotle’s first love was biology. Likely influenced by his father who was a medical doctor, nearly 1/5th of Aristotle’s extant writings describe the physiology and behavior of ~540 species. Some descriptions from his observations and dissections remained relevant and unchanged through the renaissance and even into the time of Darwin!
Formal Logic and Computation
Logic is the science of reasoning and proof, a systematic inquiry into the principles of deduction, and thus fundamental to all subsequent reasonable deductions. Aristotle (382-322 BCE) was the first to formalized logic with his 109 syllogisms, which made use of variables to represent concepts, such as in the example: all ‘A’ are ‘B’ and all ‘B’ are ‘C’, therefore all ‘A’ are ‘C’. This was well before variables were being used to represent numbers in mathematics! Aristotle thus established the first system of logic, defining the scope and rules governing logical statements. This system was considered complete and essentially closed well into the 18th century. Parallel work on logic was contributed by the Stoics and later by Galen (129-199 CE), but being difficult to merge with Aristotle’s system, it was largely ignored until the topic was intellectually revived. Indeed, it took 2,000 years before substantial challenges and additions were made to formal logic by the likes of Gottfried Leibniz, Augustus De Morgan, George Boole, Georg Cantor and Bertrand Russell, laying the modern foundation of mathematics and computation. It is also difficult to think about modern object-oriented programming and ontology design without revisting the ancient debate between modeling the world as derivatives of Forms (Plato, b.428 BCE) or as objects with properties (Aristotle, b.382 BCE).
You Call That Ancient?
Upon whose shoulders did the ancient Greeks stand? Egyptian, of course. Though neglected in most histories of philosophy, one cannot help but wonder what contributions were made by ancient Egyptians to the philosophy of science. If they had art, religion, economics, architecture, and agriculture, then surely they had science. Indeed, you may well consider Imhotep (2650-2600 BCE) to be the “Grandfather of Medicine” as his works were studied by Hippocrates. He is even indirectly mentioned in the Hippocratic Oath, being associated with (if not identical to) the Greek god of medicine, Asclepius. Imhotep was also an architect, astronomer, poet and philosopher. He was apparently an Epicurean 2,300 years before the philosophy officially existed! He promoted contentment and cheerfulness, and may have given original voice to the saying “eat, drink and be merry for tomorrow we die.”
Historians are also often remiss in examining the philosophies of ancient Asian cultures with the strict exception of religious ideas. Hinduism, for example, is the earliest of the major religions, documented in a collection of texts, the most ancient being the Vedas (2000-1200 BCE). By ~650 BCE, however, a materialistic doctrine called Lokayata was coming into bloom, its adherents were the Carvaka. They dismissed the notion of afterlife as ridiculous and relied on their senses for knowledge about the world around them. The Carvaka even attempted the same reductionist description of matter declared by Empedocles (everything being composed of earth, water, fire and air)… only they did it ~200 years earlier!
There are doubtless many other examples of parallel and preceding scientific thoughts and ideas from less documented, less preserved, and less examined cultures. Suffice it to say, the philosophy of science has many roots reaching deep and wide into human history.
Humanity of the Scientist
It is from the crucible of philosophy, flamed and annealed over millennia, that the modern scientist is formed. In fact, Science was still called Natural Philosophy in the 17th century when the modern foundations were being laid. This foundation, comprised of mathematics, experiment and systematic observation, continues to serve as a substantial base, but is itself built upon layers and layers of earlier foundations. Picture a cross-section of a London street through asphalt, cobblestone, brick and Roman quarry stone. Though perhaps discontinuous with our own, this earlier work is extremely relevant. The insights and ideas of ancient “searchers of truth” form a network of pillars and steps that not only raises the level of our modern foundation (i.e., “on the shoulders of Giants”), but also grounds it in our timeless humanity by revealing our most intimate motivations and epiphanies as apparently universal conceits of human nature. One cannot help but be amazed by just how familiar the debates, doubts and dogmas of the ancients seem today. Being able to tap into these thoughts, crystallized in such distinct settings over human history, is a valuable exercise in perspective and inspirational.
