Evidence is growing for the theory of embodied cognition, which posits that action and perception co-determine each other, forming an action-perception loop. This suggests that we humans somehow participate in what we perceive. So, how can scientists escape the action-perception loop to obtain an observer-independent description of the world? Here we present a set of conjectures informed by the philosophy of mind and a reverse-engineering of science and quantum physics to explore this question. We argue that embodiment, as traditionally understood, can manifest aspects of imaginary-time quantum dynamics. We then explore what additional constraints are required to obtain aspects of genuine, real-time quantum dynamics. In particular, we conjecture that an embodied scientist doing experiments must be described from the perspective of another scientist, which is ignored in traditional approaches to embodied cognition, and that observers play complementary roles as both objects experienced by other observers and ``subjects'' that experience other objects.

In 1929 Szilard pointed out that the physics of the observer may play a role in the analysis of experiments. The same year, Bohr pointed out that complementarity appears to arise naturally in psychology where both the objects of perception and the perceiving subject belong to 'our mental content'. Here we argue that the formalism of quantum theory can be derived from two related intuitive principles: (i) inference is a physical process performed by physical systems, observers, which are part of the experimental setup---this implies non-commutativity and imaginary-time quantum mechanics; (ii) experiments must be described from a first-person perspective---this leads to self-reference, complementarity, and real-time quantum dynamics. This approach sheds new light on the foundations of quantum theory and suggests fundamental equations in physics are typically of second order due to the physical nature of the observer. It also suggests some experimental conjectures: (i) the quantum of action could be understood as the result of the additional energy required to transition from unconscious to conscious perception; (ii) humans can observe a single photon of visible light; (iii) self-aware systems and the neural correlates of the self should be composed of two complementary sub-systems, much like the DNA molecule is composed of two strands---this may help explain the double-hemisphere architecture of the brain. Moreover, this approach may help bridge the gap between science and human experience. We discuss the potential implications of these ideas for the modern research programs on consciousness and contemplative science. As side results: (i) we show that message-passing algorithms and stochastic processes can be written in a quantum-like manner; (ii) we provide evidence that non-stoquasticity, a quantum computational resource, may be related to non-equilibrium phenomena.

After centuries of research, how subjective experience relates to physical phenomena remains unclear. Recent strategies attempt to identify the physical correlates of experience. Less studied is how scientists eliminate the "spurious" aspects of their subjective experience to establish an "objective" science. Here we model scientists doing science. This entails a dynamics formally analogous to quantum dynamics. The analogue of Planck's constant is related to the process of observation. This reverse-engineering of science suggests that some "non-spurious" aspects of experience remain: embodiment and the mere capacity to observe from an intrinsic perspective. A relational view emerges: every experience has a physical correlate and every physical phenomenon is an experience for "someone". This may help bridge the explanatory gap and hints at non-dual modes of experience.
The assumption of an objective world underlying all our experiences is deeply embedded in our everyday thinking and in our language, and has been an unquestioned presupposition of the scientific enterprise for at least four centuries. Yet it is well known that quantum physics raises some highly problematic questions in this respect, questions that are still open, almost a century from the inception of the theory. I would like to propose that these questions stem from deep philosophical assumptions and can be answered in a much more coherent way if we understand the notion of an objective world not as a primary reality, but as an emergent aspect of a primary process that can be described as “experiencing”. A coherent description of the appearance of an objective world in the process of experiencing relies on a certain understanding of what is technically known as the “quantum measurement problem”, i.e. the description of the process of observation in quantum physics, which is the key problematic aspect of the theory. I will propose that the basic features that characterize a quantum observation have a much wider scope, and describe in fact all acquisition of information by an “embodied observer”, in short all experiencing happening in the world. By applying to this larger context work I have done in the more technical frame of the quantum measurement problem it can be shown that the nature of the process of experiencing is such as to inevitably generate the appearance of an objective world. Thus the objectivity of the world, although not primary and ultimately real, is an intrinsic consequence of our “experiential embodiment”, i.e. of the fact that we are in the world and all our experiences correspond to physical happenings in the world. When examined in this perspective, the “paradoxes” of quantum physics are an invitation to abandon the metaphysical assumption of the primacy of the objective dimension of reality. A philosophical position much more in tune with quantum physics views the process of experiencing as the primary source of both subject and object, consciousness and world.
The prevailing epistemological frameworks of the twentieth century positioned the human mind as a passive receptor of objective reality—a "mirror of nature" (Rorty, 1979) tasked with accurately reflecting an external world. Yet emerging syntheses between cognitive neuroscience, phenomenology, and quantum physics suggest a radical departure from this dualistic separation of observer and observed. This paper introduces the Observer-Participant Theory, a comprehensive theoretical framework that reconceptualizes the role of awareness in human experience. The central thesis posits that conscious engagement with mental phenomena constitutes an active, participatory process that inherently shapes, modulates, and co-creates the fabric of experienced reality (Schwartz et al., 2016). The Observer-Participant Theory represents a paradigmatic shift from a classical, Newtonian model of psychology—where mental states are viewed as deterministic outcomes of biological machinery—to a quantum-neurodynamic model. Here, consciousness is not a passive epiphenomenon but an active agent in the construction of subjective reality (Wallace, 2007). This paper argues that directing conscious attention toward internal or external phenomena is never a neutral measurement; rather, it constitutes an energetic intervention that influences the ontology of what is observed. Awareness operates not merely as a window through which reality is perceived, but as a dynamic force through which reality is continuously crafted, refined, and actualized (Pribram, 1991).
