Spatial models dominated memory research throughout much of the 20th century, but in recent decades, the concept of memory as a form of mental time travel (MTT) to the past has gained prominence. Initially introduced as a metaphor, the MTT perspective shifted the focus from internal memory processes to the subjective conscious experience of remembering. Despite its significant impact on empirical and theoretical memory research, there has been limited discussion regarding the meaning and adequacy of the MTT metaphor in accounting (...) for memory. While previous work has addressed the general limitations of the MTT metaphor in explaining memory (Trakas, 2022), the objective of this article is more focused and modest: to gain a better understanding of what constitutes MTT to the past. To achieve this objective, a detailed analysis of the characteristics of MTT to the past is presented through a comparison with time travel (TT) to the past. Although acknowledging that TT does not refer to an existing physical phenomenon, it is an older concept extensively discussed in the philosophical literature and provides commonly accepted grounds, particularly within orthodox theories of time, that can offer insights into the nature of MTT. Six specific characteristics serve as points of comparison: (1) a destination distinct from the present, (2) the distinction between subjective time and objective time, (3) the subjective experience of the time traveler, (4) their differentiation from the past self, (5) the existence of the past, and (6) its unchangeability. Through this research, a detailed exploration of the phenomenal and metaphysical aspects of MTT to the past is undertaken, shedding light on the distinct features that mental time travel to the past acquires when it occurs within the realm of the mind rather than as a physical phenomenon. By examining these characteristics, a deeper understanding of the nature of mental time travel is achieved, offering insights into how it operates in relation to memory and the past. (shrink)

The value of the notion of ‘indeterminacy in the past’ continues to be contested. Ian Hacking’s claim that the notion is perspicuous in the examination of historical instances is questioned through discussion of the possibility of retrospective application of the relatively recent diagnostic category ‘Post-traumatic stress disorder’. Kevin McMillan maintains that there are deeper philosophical merits to the idea–particularly with respect to questions of truth–but neither Hacking’s treatment of historical cases nor McMillan’s directly philosophical elaboration of Hacking’s position sustain this (...) claim.

The voices and visions experienced by Emanuel Swedenborg remain a topic of much debate. The present article offers a reconsideration of these experiences in relation to changes in psychiatric practice. First, the phenomenology of Swedenborg's experiences is reviewed through an examination of his writings. The varying conceptualizations of these experiences by Swedenborg and his contemporaries, and by psychiatrists of later generations, are examined. We show how attempts by 19th- and 20th-century psychiatrists to explain Swedenborg's condition as the result of either (...) schizophrenia or epilepsy are unable to account for his experiences. We then demonstrate that the re-emergence of the 19th-century concept of `hallucinations in the sane' offers an alternative way to understand Swedenborg's experiences outside typical discourses of mental illness. Finally we argue that Swedenborg's experiences should be understood as exemplifying phenomena which we term `hallucinations without mental disorder', and investigate how conceiving of Swedenborg in this way can inform future research into the experience and clinical significance of hallucinations.

In chapter 17 of his book, Rewriting the Soul: Multiple Personality and the Sciences of Memory , Ian Hacking makes the disquieting claim that “perhaps we should best think of past human actions as being to a certain extent indeterminate.” 1 Against what may appear like the self-evident conception of the past as fixed and unalterable, Hacking suggests that when it comes to human conduct and experience, there are reasons to adopt a more flexible view. This suggestion (...) has caused lively debate, in the journal History of the Human Sciences and elsewhere. 2 Central to this debate is the question of what it means to use a recently invented vocabulary to redescribe past human affairs. In particular, it is asked: How do the linguistic, cultural and social differences between past and present matter to the possibility of such a redescription's being true? We who do research in the humanities and social sciences often make retroactive redescriptions of precisely this sort. Hence, the debate is clearly of some general importance for how to conceive the goals and methods of our inquiries. My overall aim in this paper is to clarify what we may learn from the clash between Hacking and his critics. (shrink)
