"I do not conceive of any reality at all as without genuine unity" – Gottfried Leibniz
Going a step further than the idea that there are connections between some fields is to suggest that all fields are inextricably connected - as demonstrated by Aristotle's 'Tree of Life' and more recently Fritjof Capra's ‘Web of Life'. A.J. Jacobs, editor of Esquire, who as a part of one of his "lifestyle experiments' chose to read the entire Encyclopedia Britannica, concluded that: 'everything is connected like a worldwide version of the six-degrees-of-separation game'. Edwin Hubble recognised that the perception and segmentation of knowledge is simply a man-made pro-cess, whereas reality is actually one unified whole. 'Equipped with his five senses', he said, 'man explores the universe around him and calls the adventure Science'.
This human obsession with the compartmentalisation and branding of fields and disciplines - fuelled in part by the 'information explosion' - is a relatively recent adoption by society and thus by the human mind. Before the European Enlightenment, disciplinary boundaries were not rigidly fixed and it was therefore easier to pursue multiple fields of study without the "dangers of straying'. In fact there was no such notion as 'straying there existed a recognition that everything in the cosmos was inextricably connected in a way that necessarily required the investigation of multiple aspects of it. This holistic approach to life and thought was considered the norm for the earlier polymaths for whom the unity of knowledges, branches on a common tree, reflected the unity of the cosmos!
The prevailing philosophy of each society in human history has had some part to play in encouraging polymathy, albeit for differing reasons. But there is a common thread weaving through each of these world views, regardless of time and place. This thread is the holistic outlook - one that can be found in Ancient Egyptian, Greek, Roman, Christian, European Renaissance and West African Yoruba philosophies, as well as in Confucian, Taoist, Islamic, Hindu, Polynesian and Mayan cosmological frameworks. Historian of science and Islamic philosopher Seyyed Hossein Nasr confirms this:
One might say that the aim of all Islamic sciences - and, more generally speaking, all of the medieval and ancient cosmological sciences - is to show the unity and interrelatedness of all that exists, so that, in contemplating the unity of the cosmos, man may be led to the unity of the Divine Principle, of which the unity of Nature is the image.
For example, the Islamic concept of Tawheed, which alludes to the oneness of God and the unity of the cosmos was what motivated an entire era of Muslim polymathy. Nasr elucidates:
Tawheed in Arabic not only means unity but 'to make one' -integration. So integration was one of the most important consequences of Islamic Revelation. The Quran itself and its message of unity is why classical Islamic civilisation always emphasised the importance of polymathy and was why it produced so many polymaths.
While Muslims in fact became known as the muwahidun or the 'unifiers, such unity of this Divine Principle was recognised in most societies: to Aboriginal tribes it was arungquiltha, to Polynesian tribes mana, to Mesoamerican tribes waken. As Frijof Capra, physicist and author of the Tao of Physics confirms:
The fundamental interconnectedness of all phenomena, which is the central insight of polymaths who are systemic thinkers, is also the fundamental insight of Eastern spiritual traditions, from Hinduism and Buddhism to Taoism.
The thirteenth-century Christian philosopher and polymath Thomas Aquinas described how theology could bring all our areas of knowledge together, offering a glimpse of God's own knowledge, which is the single and simple vision of everything'. Influenced by this, Cambridge scholar Keith Eyeons, author of The Theology of Everything, explains how the Divine Unity was seen by Christian polymaths as the original source, and how that naturally inferred the interconnectedness of everything:
God is the source of the rational structures of the universe investigated by scientists. God also has a glory and a beauty which is partly glimpsed through creation. Furthermore, God is love, and the Christian belief in the Trinity suggests that there are relationships of love within the threefold nature of God. Human relationships and communities therefore reflect something of the character of the divine consciousness which shapes the universe. Combining those theological ideas indicates that, for example, physics, art, and friendship are all connected.
Whether or not Leonardo da Vinci, our quintessential polymath, held the same outlook because of his Christian beliefs is not clear. We do know, however, that he was interested in the holistic ideas of the East. Martin Kemp, the world's foremost expert on Leonardo confirmed this:
Leonardo spoke to sea captains to enquire about other cultures. He would have been particularly interested in the more holistic philosophies which often characterised thought outside of European specialised thought, and thought in which rather the rigid procedures of empirical data are less prevalent and less dominant.
In contending that everything is inextricably connected, Leonardo believed strongly that one discipline could not be fully understood without the firm comprehension of several others. He often pointed to the fundamental connections between painting, music, poetry, philosophy and science. 'He who despises painting loves neither philosophy nor nature" he said, 'music may be called the sister of painting' and 'if poetry treats of moral philosophy, painting has to do with natural philosophy. The entire world (and the knowledge of it), according to Leonardo, is one big (Italian!) family. Indeed, it is because he didn't see things in categories that his notes seem so sporadic - he switched between subjects naturally because he saw everything as connected. As Kemp says:
Leonardo was a kind of pathological lateral thinker . . . so when exploring anatomy, he'll be looking at the heart, the movement of water . . . And when exploring movement of water, he'll be thinking about the curling of hair, and so on - it would be an infinite spiralling on of these related interests, and underneath all this variety there is a common thing, a cause and effect.
But the holistic outlook is by no means exclusive to ancient, premodern philosophies and religious cosmologies. It is also a feature of the modern scientific paradigm. E.O. Wilson, regarded by many as one of the world's leading scientists and a champion of reason and the scientific method, himself calls for the unity of knowledge in his book Consilience. 'A united system of knowledge', he argues, 'is the surest means of identifying the still unexplored domains of reality'. This world view, according to E.0. Wilson, is the natural state of the human conscience. He emphasises that the unification of knowledge 'gratifies impulses that rise from the admirable side of human nature' and in fact 'eives ultimate purpose to intellect'.
Many of the world's greatest thinkers in the history of modern Western science and philosophy have commented on the usefulness (and sometimes indispensability) of this outlook. Again, it is of no surprise that many of these were in fact polymaths. Goethe saw nature as 'one great harmonious whole' and Humboldt had a 'habit of viewing the Globe as a great whole'. Buckminster Fuller emphasised the world as being a single entity or an 'unfragmented whole' and expressed a firm belief in its absolute unity and the consequent need for the 'comprehensivist' - someone likely to have a more rounded understanding of the cosmos. It is a method of thought that treats everything in the world as part of one single field within which everything is interconnected.
Although holism is an ancient philosophy with its roots in Hindu cosmology, it has been an essential aspect of Western thought for centuries (Kant, Spinoza, Hegel and Nietzsche were heavily influenced by it). In fact 'holism' as a philosophical term was coined by none other than one of the twentieth century's eminent polymaths, Jan Smuts, who in his book Holism and Evolution (1927) called for the unity of all things and knowledge. It alludes to what scientists, artists and philosophers have long considered to be a 'vanishing point' - a geometric notion with philosophical implications, where all of our particular areas of enquiry, knowledge and understanding eventually converge.
This insistence on the inseparability of various seemingly disparate domains is still shared by many of today's polymaths, whether scientific or artistic. 'I see everything as connected, and I am motivated to look for connections largely because nothing makes sense to me in isolation', says philosopher and polymath, Roger Scruton. 'Many scientists acknowledge this. Not only can you not understand biology without seeing it in terms of the laws of physics, the laws of physics must themselves be understood in
terms of their application in biology'.
When asked about which from acting, poetry, music and painting was his favourite, artistic polymath Vigo Mortensen replied: "I don't really separate them; they are all the same thing'. Another artistic polymath Billy Childish feels similarly: I don't identify myself as a writer or painter or musician, but as someone on the path to realisation. For me it's a spiritual life path'. Creativity to such individuals also comes naturally. David Stewart, the musician often described as a modern 'Renaissance man', said, 'People talk about thinking outside the box? Well, for me, I never even saw a box’.
