There is a two times problem: human time has not been reconciled with physical time. Many physicists insist that the human experiential ‘flow’ (and ‘passage’) of time are illusory phenomena. Neuroscientists most often take a completely opposite point of view. As a compromise the Dualistic Mind view claims that the brain possesses a veridical system of major parameters of time but also a corresponding illusory system of parameters for the purposes of better adaptation and action. Continuity illusions are said to be, in large part, responsible for the illusory nature of these temporal parameters. The net result is that the ‘flow of time’ and the ‘passage of time’ have a unique reality in the agency of time perceivers. This is an update to our previous views on the dualistic model. The dualistic nature of seven major temporal parameters were analyzed, particularly concerning the experiential illusory continuities that are involved in them. These dualistic parameters include movement/motion, temporal order/temporality, and persistence/ephemerality. For example a cerebral add-on of continuity illusions (of the ‘apparent motion’ type) to veridical movement begets an illusory experiential motion. Ephemerality/persistence is another dualistic parameter for the observer in a simple spacetime scenario to negotiate one ‘present moment’ to the next. It explains Einstein’s ‘stubborn illusion’ of the past/present/future of time. Temporality/temporal order is yet another dualistic parameter which involves the ‘feeling of succession’ acting as a continuity illusion. These dynamistic experiences are all contributors to the ‘flow of time.’

A possible solution is offered to help resolve the “two times problem” regarding the veridical and illusory nature of time. First it is recognized that the flow (passage) of time is part of a wider array of temporal experiences referred to as manifest time, all of which need to be reconciled. Then, an information gathering and utilizing system (IGUS) model is used as a basis for a view of manifest time. The model IGUS robot of Hartle that solves the “unique present” debate is enhanced with veridical and (corresponding) illusory components of not only the flow of time but also the larger entity of manifest time, providing a dualistic IGUS robot that represents all of the important temporal experiences. Based upon a variety of prior experiments, that view suggests that the veridical system is a reflection of accepted spacetime cosmologies and through natural selection begets the illusory system for functional purposes. Thus, there are not two opposing times, one outside and one inside the cranium. There is just one fundamental physical time which the brain developed, now possesses and is itself sufficient for adaption but then enhances. The illusory system is intended to provide a more satisfying experience of physical time, and better adaptive behavior. Future experiments to verify that view are provided. With a complete veridical system of temporal experiences there may be less need to reify certain temporal experiences so that the two times problem is less of a problem and more of a phenomenon.

There is a long standing debate as to whether or not time is ‘real’ or illusory, and whether or not human time is a direct reflection of physical time. Differing spacetime cosmologies have opposing views. Exactly what human time entails has, in our opinion, led to the failure to resolve this ‘two times’ problem. To help resolve this issue we propose a dualistic model of human time in which each component has both an illusory and non-illusory aspect. With the dualistic model we are able to provide experimental tests for all of the human time assertions of 10 chosen spacetime cosmologies. The illusory aspect of the ‘present,’ i.e. a ‘unique present’ was confirmed. An information gathering and utilizing system was constructed using a virtual reality apparatus allowing the observer to experientially roam back and forth along the worldline ad lib. The phenomenon of ‘change’ was experimentally found to be illusory at high frequency observation and non-illusory at low frequency observation, the latter phenomenon coinciding with ‘change’ referred to in the ‘Order of Time’ and ‘Relativity Refounded’ views. Additional experiments are presented indicating that both motion and temporality are dualistic. In sum, the dualistic model of human time allows for the existence of both illusory and non-illusory aspects of human time that are not in conflict with one another. It also provides experimental evidence for various spacetime cosmological assertions regarding human time.

Perceptual completion fills the gap for discrete perception to become continuous. Similarly, dynamic perceptual completion provides an experience of dynamic continuity. Our recent discovery of the ‘happening’ element of DPC completes the total experience for dynamism in the flow of time. However, a phenomenological explanation for these experiences is essential. The Snapshot Hypotheses especially the Dynamic Snapshot View provides the most comprehensive explanation. From that understanding the ‘two times’ problem can be addressed. The static time of spacetime cosmologies has been irreconcilable with the dynamic FOT. Dismissing the FOT as an illusion is unsatisfactory. Therefore, we provide four hypotheses for the TTP.1) Since cosmological static time demands that all events are discrete, DPC elements for dynamism should likewise be expected to be discrete and accounted for by a snapshot phenomenology such as the DSV. 2) If temporality can be demonstrated to be similar to apparent motion by being a snapshot phenomenon and not demanding temporal extension it would confirm the DSV and permit reconciliation with static time. 3) If the ‘present moment’ is subjective as static time theories suggest, it should be possible experimentally for an observer to choose his own ‘present’ by moving to various points in the past with the aid of virtual reality. 4) If dynamism e.g. motion can be precluded without significant information loss or violating physics principles it is a cognitive add-on, thereby contradicting non-static time theories which suggest that time is ‘real.’ We confirm those hypotheses.

Many physicists regard the flow of time as an illusion. There is an upper level flow of time, the phenomenon of past/present/future; and there is a lower level flow of time which is really a flow of events. Perceptual completion accounts for the lower level flow of time in a few ways: apparent movement; amodal completion; and dynamic change as exemplified by a newly described modal completion that we called happening. It acts like an illusory percept connecting discrete stimuli in all sensory modalities. The past/present/future distinction cannot exist unless an object is perceived to be the same now as it is then. This cognition requires object persistence. Experiments with object persistence suggest the circumstances when that, too, is an illusory percept. The illusory percepts of object persistence and perceptual completion can account for the entire flow of time. Our findings and conclusions are congruent with a few time theories and cosmologies that suggest that the flow of time is an illusion.

Michael A. Jawer and Marc S. Micozzi present a broad analysis of emotions and feelings as they connect to both the brain and body in The Spiritual Anatomy of Emotion. As an additional feature, the authors attempt to relate emotions to what they call the sixth sense — the spiritual. This book is a comprehensive collection of opinions, anecdotes, and scientific studies; the authors weave these into the supporting structure of their theory. The book is a comfortable, easy read; it is well-organized and referenced from beginning to end. It is appropriate for both professionals and academics in the fields of neuroscience and cognitive science, yet at the same time does not exclude a much larger audience — the educated public

Three physical theories explaining the flow of time are examined. One theory suggests that “flow” is associated with the manner of information transfer between registers within the brain. Different robotic systems are predicted to experience different types of flow. Here, human examples are found to support the theory and the model is modified suggesting that flow is a cognitive illusion. A second theory suggests that time is non-existent, that the universe is a complex quantum state which, upon observation, the brain acquires “stills” and converts them to an illusion of motion and flow. Accordingly the brain should be able to generate a physiological illusion of temporality from stills. Experimental evidence is given that the temporality illusion so generated is not physiological; it is cognitive, lending no support to that theory. A third theory suggesting that the flow of time is really a myth is briefly reviewed
