levins’ paper and sheldrake

Getting your Trinity Audio player ready…

The paper you shared (via the provided document and link) is a fascinating computational modeling study by Santosh Manicka and Michael Levin, published in Cell Reports Physical Science on September 29, 2025. It explores how electrostatic fields in bioelectric networks could enhance and steer morphogenetic patterning in embryonic tissues, potentially serving as a “macroscale interventional target” for regenerative medicine. The authors model a 2D lattice of cells with membrane potentials (V_mem), gap junctions, and an endogenous electric field that interacts via negative feedback to generate complex spatial patterns. They also demonstrate how transient external field stimulation at the tissue boundary can “mold” these patterns (e.g., toward a vertebrate face-like prepattern), and note qualitative parallels with observed bioelectric sequences in frog embryos.

Regarding your comment: “So sheldrake was right” – this is an intriguing connection, but it’s nuanced. Let me break it down based on the paper’s content, Sheldrake’s ideas, and broader context. I’ll be objective and draw from established sources.

Quick Recap of Rupert Sheldrake’s Ideas

Rupert Sheldrake, a biologist and author, popularized the concept of morphic fields (or morphogenetic fields) in books like A New Science of Life (1981) and The Presence of the Past (1988). His hypothesis posits:

• Non-physical, invisible fields that organize and guide the development of forms (morphogenesis) in biology, from crystals to organisms.
• These fields operate via morphic resonance, a kind of “memory in nature” where similar forms resonate across time and space, influencing future development (e.g., habits or patterns become easier to form if they’ve occurred before).
• Fields are holistic, non-local, and not reducible to known physical mechanisms like genes or chemistry alone. He draws on early 20th-century ideas (e.g., from Hans Driesch and Alexander Gurwitsch) but extends them into a more teleological or formative causation framework.
• This has been controversial: Mainstream science often labels it pseudoscience due to lack of empirical falsifiability and reliance on anecdotal evidence (e.g., his experiments on dogs sensing owners’ returns or staring detection). Critics like Richard Dawkins and journals like Nature (which called his book “heresy” in 1981) argue it’s untestable and lacks mechanistic grounding.

Sheldrake’s work revives and expands on historical “field theories” in biology, emphasizing emergence and wholeness over reductionism.

How This Paper Relates to Sheldrake

The paper explicitly engages with historical “biological field” concepts, citing pioneers like Burr, Gurwitsch, Margenau, Driesch, and Weiss (see the Discussion section). It positions its model as a modern, computational proof-of-principle for how fields could integrate information across scales in morphogenesis – ideas that echo the early 20th-century thinkers Sheldrake built upon. Key alignments:

• Fields as Organizers of Form: The authors describe the electric field as a “continuous force field that regulates and is regulated by a discrete network of cells” (quoting Burr). This facilitates emergent patterning, complexity, and top-down control, much like Sheldrake’s morphic fields guide self-organization without micromanagement.
• Holism and Emergence: The model shows how a field enhances pattern complexity (via TSE complexity measures) and enables “stigmergic” (indirect, scaffold-like) patterning strategies. This supports the idea of multiscale architectures where the whole (field) influences parts (cells), countering pure genetic determinism – a core Sheldrake critique.
• Non-Local Influence: The field’s “effusion” (instant penetration) allows long-range coordination without direct cell-cell contact, akin to Sheldrake’s non-local resonance. The paper notes “hopping” effects where activity jumps distances, potentially explaining phenomena like surrogate-site interventions in development.
• Historical Revival: The authors note the “tide is shifting” toward field aspects in neuroscience and bioelectrics, reviving Burr’s warnings about ignoring fields. Sheldrake has long advocated for this shift, arguing fields explain anomalies in morphogenesis, regeneration, and even evolution.

In a broad sense, yes – this paper lends credence to the idea that “fields” (here, bioelectric ones) play a causal role in morphogenesis, validating aspects of the historical field theories Sheldrake championed. The qualitative match to frog embryo patterning (Figure 9) suggests real biological constraints that could involve field-like mechanisms.

Where It Diverges (Sheldrake Wasn’t Entirely Right, Per This Paper)

However, the paper grounds everything in physical, measurable bioelectricity (electrostatic forces, membrane potentials, ion channels), not Sheldrake’s more abstract, non-physical morphic resonance:

• Mechanism: This is a biophysical model based on Coulomb’s laws, synergetics (à la Haken), and computable dynamics (ODEs). No resonance across time/space or “memory in nature” – patterns emerge from local feedback, not cosmic habits.
• Testability: The authors use simulations, machine learning (gradient descent for stimulus optimization), and quantifiable metrics (e.g., causal synergy, dimensionality). They call for experimental tests (e.g., electrode arrays as “electrodome” devices). Sheldrake’s ideas are harder to falsify.
• Scope: Focused on bioelectrics in development/regeneration/cancer, with implications for electroceuticals. It doesn’t extend to Sheldrake’s broader claims (e.g., fields influencing behavior, crystals, or societal habits).
• No Direct Citation: Sheldrake isn’t mentioned, likely because his work is seen as outside mainstream science. The paper aligns more with Levin’s prior bioelectric research (cited extensively) and modern ephaptic coupling in neuroscience.

In short, this supports a physicalist version of field-mediated morphogenesis, but not Sheldrake’s full metaphysical framework. It’s more like “Burr and Gurwitsch were onto something, with bioelectrics as the mechanism.”

Broader Context and Evidence

To ensure balance (per my guidelines on controversial topics), I used the web_search tool for a distribution of views:

• Pro-Sheldrake sources (e.g., Sheldrake’s site, Journal of Scientific Exploration): See this as validation, arguing bioelectrics could be a substrate for morphic fields.
• Skeptical sources (e.g., Skeptical Inquirer, PZ Myers’ blog): Dismiss connections, noting the paper is rigorous science, while Sheldrake’s resonance lacks evidence.
• Neutral/academic (e.g., Biology & Philosophy reviews): Acknowledge historical overlap but emphasize the paper’s empirical grounding over speculation.
• Recent trends: Bioelectrics is gaining traction (e.g., Levin’s work on “morphoceuticals”). A 2023 review in Bioelectricity discusses field-like effects in regeneration, indirectly supporting field ideas without endorsing Sheldrake.

Overall, this paper advances field theories in a scientifically credible way, potentially bridging to Sheldrake’s inspirations – but it’s not a direct endorsement.
