This article explores the profound impact of visualism and visual perception in the context of medical imaging diagnostics. It emphasizes the intricate interplay among vision, embodiment, subjectivity, language, and historicity within the realm of medical science and technology, with a specific focus on image consciousness. The study delves into the role of subjectivity in perception, facilitating the communication of opacity and historicity to the perceiving individual. Additionally, it scrutinizes the image interpretation process, drawing parallels to text interpretation and highlighting the influence of personal biases and individuality in medical practice. By revisiting Husserl’s conceptualization of “image consciousness” and introducing the notion of “image theme”, the paper seeks to establish a theoretical framework for making sense of images within the context of technological interpretation. A key objective is to enhance the phenomenology of technology through a systematic analysis of medical imaging diagnosis, contributing to an expanded epistemological foundation for medical practice. The article recognizes that the construction of medical knowledge incorporates subjective elements, especially within a historical context. The interpretation of images involves both instrumental and expert interpretation, with human subjectivity playing a crucial role. The article asserts that human creativity and conscious engagement are indispensable in interpreting all medical images.

The leap from primitive to scientific time represented as the “time” in “relativity physics,” or in “thermodynamics” or perhaps in “quantum physics” or even within “statistical mechanics” is large. Large also is the conceptual difference between these various understandings of the nature of time. How are we really to understand these physical perspectives on time: As knowledge about the real nature of time represented by the objective concepts: Or as epistemological-operational abstractions that cannot avoid elevating their results to the level of full-fledged reality, to ontology?

Embodied cognition is an interpretative—or hermeneutical—cognition inherent in motor-sensory perception intrinsically informed by biological and sociocultural memory, a cognition embedded in the organism as well as the socio-cultural environment interacting with it (Ward et al. TOPOI 36:365–375, 2017), of which technologies are a part. Yet, smart machines are advancing on human abilities to perceive and interpret concerning the accuracy, quantity, and quality of the data processed. Machines process and categorize images, perform classification tasks, they calculate and perform pattern analysis, all machine learning processes are task-specific. Machine learning processes resemble human interpretative processes; however, these are two very different ways of “dealing with something,” although both can be said to be hermeneutical, one enactive, the other material; the first is a meaning-generating interpretative process, the second a statistics-based information output. The information extracted from all the data fed into the computer is the end-product of machine learning, whereas human interpretative enactments are continuous and necessary for any application of the information output.

Generally speaking, the most essential and characteristic feature of realism is the notion of a mind-independent existence, which means that individual or a species of things have an existence that is “in-itself”. Realism is a metaphysical position; it is a stance taken of individual mind-endowed human beings towards the world in perception. On the other hand, to deny that something is mind-independent is yet another, however different, metaphysical stance that is called anti-realism or idealism. However, philosophical discourse discloses the fact that we, as philosophers and scientists, tend to choose different specifications for what is to count as “independent of mind” and also in which way this “mind-independent” entity is supposed to exist. There are many metaphysical issues over which realism and idealism have been argued. For example, we have the question about the existence of moral values. Or we have the problem of the existence of souls and minds. More interestingly is whether the past can be said to have been real, or, on the other hand, if the future is real. We tend, nevertheless, to take different specifications for granted and therefore we have a tremendously large variety of senses in which the word “realism” is being used. In order to get a general feeling of the modern sense of philosophical realism, we have to briefly take a look at the “before” and “after” of Kant.

In this commentary on Don Ihde’s paper “Stretching the in-between: embodiment and beyond” I argue that perceptions and observations are based on tacit frames and these frames are expressed through pre-reflexive intuitions thus giving meaning to the perceived content of observations. However, if the objective or given information in perception is incomplete or missing our brain and nervous system will intuitively and unconsciously fill in the missing information in order to act—these particular pieces of added information may not be relevant to the decoding of the given content of perception at all.

In this paper I will argue that medical specialists interpret and diagnose through technological mediations like X-ray and fMRI images, and by actualizing embodied skills tacitly they are determining the identity of objects in the perceptual field. The initial phase of human interpretation of visual objects takes place during the moments of visual perception before we are consciously aware of the perceived. What facilitate this innate ability to interpret are experiences, learning and training that become humanly embodied skills. These embodied skills are actualized during the moments of visual perception. My argument is that biology, society and instruments constitute unique individual ontologies influencing specialist readings of the technological output, in other words, putting limits on the ‘‘truth-to-nature’’ relation, which is so much sought for in science.
