As part of the Projective Geometry Conference, the Natural Science Group of the Anthroposophical Society in Great Britain presents: The Organic Geometry

Lecturer: Russell Arnold, Mathematician at the Section for Mathematics and Astronomy at the Goetheanum

The families of shapes known as path curves and path surfaces contain a remarkable variety of forms found in living nature, as demonstrated by Lawrence Edwards following the inspiration of George Adams. This talk will look at the historical, mathematical and morphological context of these shapes.

Friday 27 June 2025, 19.00 - 20.30

The Field Centre, Nailsworth GL6 0QE

Free lecture. Contributions welcome.

What Relationship Does the Inverse Spectra of Goethe's Theory of Colours Have to the Duality of Projective Geometry?

In Goethe’s theory of colour we find two spectra: the rainbow spectrum (Newton’s spectrum) with green in the middle, and the “inverted spectrum” with magenta in the middle, which is also called the “inverse spectrum” or “Goethe’s spectrum”. In today’s optics, it is known that the two spectra are mutually dependent as complements that are — at least phenomenologically — equivalent. 

 At about the same time the duality principle in geometry was formulated, thereby founding projective geometry. Rudolf Steiner repeatedly pointed out the importance of projective geometry for understanding life processes, and he coined the term “counterspace” in this context. Research was done on both fields since decades, often also in local and inner proximity, like in the case of Michael Wilson and George Adams at Sunfield. Yet, both research questions were not often addressed together. Against this background, the question arises as to the relationship between the optical complementarity of the inverse colour spectra and the duality of projective geometry. Can the physical-mathematical description of light and colour be extended by a view and/or description of counterspace?

About Dr Mattias Rang

Matthias Rang studied physics in Freiburg, Germany and Berlin before becoming a visiting researcher in the field of nano-optics at the University of Washington, Seattle. He received a PhD from the University of Wuppertal, Germany. At the Goetheanum in Dornach, Switzerland, where Rang co-leads the Natural Science Section, he carries out research on Goethe’s theory of color in relation to physical optics.. 

Are fungi and plants intelligent? How does animal intelligence relate to human intelligence? Many popular books today address such questions, and intelligence in nature is the focus of ardent debate within mainstream science. With the current discussion as a starting point, Craig Holdrege will explore what intelligence could mean in plants, animals, and humans. His guiding question is: How can we gain understanding in a way that does justice to the diverse ways of being found in the world?

All welcome.

Craig Holdrege, Ph.D., is co-founder and director of The Nature Institute in Ghent, NY, an organization dedicated to developing a phenomenological and participatory understanding of the natural world (natureinstitute.org). He is deeply interested in the interconnected nature of things and how we can understand life in truly living ways as a basis for responsible human action. His studies of plants and animals, as well as his commentaries scientific thinking and new developments in the biological sciences, aim to stimulate a transformation in human thinking and perception. Craig is the author of many articles, monographs, and books, including Thinking Like a Plant: A Living Science for Life and Seeing the Animal Whole – And Why It Matters. He gives talks, workshops, and courses nationally and internationally.

Greenhouse or Mirror with Window? An Optical Approach to Understanding the Earth’s Atmosphere

Viewing the thermal regulation of the earth from the perspective of optics is surprisingly straightforward. Surrounded by a vacuum, the earth’s thermal exchange with the cosmos occurs entirely via light and heat radiation. The climate crisis is thus an expression of a changing relationship of the earth to the cosmos that can be described optically: the earth’s atmosphere is increasingly losing the capacity to be a window to the cosmos and is increasingly becoming a mirror. In this lecture we will consider phenomena, in part from daily life, with which we can develop a characterisation of the the earth’s thermal mantle.

This event is open to anyone interested in a hands-on experience of “hominid” fossils. I will be displaying exact museum casts of key specimens that have informed current thinking on ancient humans. We will make observations and comparisons, and discuss how the specimens contributed to paradigm shifts and controversies in human evolution research. We will consider the anatomy, posture and way of life of these ancient creatures and one main focus will be the well-known discussion on brain size, hand dexterity and bipedal posture. No prior knowledge is assumed.

Dr Judyth Sassoon

A presentation and discussion at The Field Centre exploring human evolution.

All are welcome.

In his commentary on Goethe’s Scientific Writings, Rudolf Steiner remarks apropos the structure of the Didactic Part of the Farbenlehre that the “impulse of the age that led to the architecture of Hegel’s whole system is obvious in this path moving from subject to object and back again”.

This “impulse of the age” did not only lead to Goethe’s Farbenlehre and Hegel’s Phenomenology of Spirit—we also find it developed in the evolutionary thought of Owen Barfield, which his fellow Inkling J.R.R. Tolkien brought to expression in his increasingly popular Legendarium. In this lecture we will consider the structure of the Didactic Part of Goethe’s Farbenlehre as an evolution of consciousness and then compare this with Owen Barfield’s conception of evolution (with a short intermezzo on the Phenomenology and history of the elves).

This presentation draws on the work of Jochen Bockemühl, whose pioneering approach to place and landscape studies is informed by both J. W. Goethe and Rudolf Steiner. Bockemühl, in employing the fundamental principles of Goethe’s work, further enhanced his approach through Steiner’s meditative indications. Bockemühl considered his approach to be a ‘holistic mode of observation’. In his Awakening to Landscape, Bockemühl proposes that “A holistic study of nature begins' by gaining further experience in moving from phenomenon to inner vision and then makes this its guide in turning the eye back to the phenomenon.” There are three stages implicit in Bockemühl’s articulation; three stages that form a continuum. These are (1) studying the phenomenon, (2) moving from the phenomenon to inner vision, and (3) turning the eye back to the phenomenon. This presentation explores the stages of this iterative cycle in relation to the question of place.

All are welcome.

Maker’s knowledge (artisanal epistemology) is the embodied knowledge of craftspeople, gained by virtue of their physical engagement with a particular craft. It points to a recent realisation that the production of material objects requires large-scale experiential knowledge that is complex, innovative, methodical and evolving. Here, I will speak about the importance of maker’s knowledge in general and also highlight its role in furthering science in the early modern period and its recent use as a research method for understanding human culture in the past. All the examples I use refer to human engagement with rocks and minerals.

All are welcome.

Goethean science is often characterised as a qualitative approach to science. What exactly this is supposed to mean is rarely spelt out, but generally implied is some kind of opposition to quantitative or mathematical approaches to science. Viewing Goethean science in opposition to mathematics may certainly be helpful for gaining an initial understanding of what it is, but taking this distinction as essential impedes not only a deeper understanding, but also its subsequent development. 

 In the first half of this talk we will compare the polar structures of colour and space to show that connecting Goethe’s colour studies to nineteenth century developments in mathematics, specifically projective geometry, can enrich our understanding of polarity. In the second part of this talk we will compare sequences generated by geometrical transformation and plant development to show that the practice of projective geometry can help sensitise us to the metamorphosis of plants.

Nature’s importance for human well-being has a high media profile and there is a growing call for a deeper, more connected relationship with the animals and plants around us. But what about the past? Does the past matter and what kind of relationship can we have with the creatures of earth’s deep history? What is the ontological status of animals and plants that are only known to us through fossils?  Referring to Goethe’s work on animal and plant archetypes, I will present some of my recent research and discuss the role of “typological thinking” in how we think about and relate to extinct animals.

Barry Lopez once pointed out that we have developed a relationship to the experienced world in which we would rather think about the fox slinking through the meadow, than be with the fox slinking through the meadow. This preoccupation with our own thinking has the tendency to blind us to the qualitive differences apparent in the world around us. Rudolf Steiner called attention to the fourfold expression of being on earth with his remarks concerning mineral, plant, animal and human. These express themselves in qualities of form, life, sentience and intention. By attuning ourselves to the nature of these different qualities, we can become more aware of the nature of our relatedness to the wholeness of which we are also a part and begin to learn from the world what it needs of us.

The School of Spiritual Science is a framework of understanding and practice which can support every human being in awakening to itself and a deeper understanding of the world. The School invites all those who are interested in self-mastery, to actively participate in furthering the dignity and responsibility of human beings, as integral co-learners and co-creators of an emergent and interconnected future. As evolving soul-spiritual beings, we may become ever more aware of the interrelationships of all things… 

In this session, we will introduce some core qualities of this work and invite you into an open conversation of exploration. Together we will look at the value of tuning ourselves as instruments of perception, in the practices of observing, reflecting, resonating, contemplating and articulating.  We intend to explore how we might create a mood and find a language which may open such spaces in which soul-spiritual perception can unfold. 

We warmly invite you to join us on this journey, as apprentices of life.
