It follows from the temporal nature of mind—the main concern of this essay—that mind functions are not localized in brain space.“ Time is extendedness, probably of the mind itself”, concludes Saint Augustine in Book XI of his Confessions (26.33), and, in our days, this extendedness can be made visible through an oscilloscopic “line” or trace of slow potentials. These graded, additive (not all-or-none) autorhythmic and seemingly self-generating potentials are primary events recorded at synapses. Autorhythmic brain structures (Zabara, 1973) appear to (...) be the source of time frames, while a change in time frames (as reflected in the EEG) leads to synchronization and desynchronization of brain structures respectively. Synchronization forms a homogeneous time domain, such as obtained during rhythmic exercises, chanting, listening to music and mental processes that are the hallmark of religious practices (Rogers, 1973). Desynchronization of brain structures on the other hand marks a functional independence of neuronal elements with each element available for separate channels of data processing, for example, during hallucinogenic drug-induced central sympathetic arousal, that is, a waking dream state (Fischer, 1979).

The temporal orientations of any sociocultural grouping are major factors comprising its central identity. The manner in which the past (memories), the present (perception), and the future (anticipation/expectation) are commonly articulated also concern cultural identity. The identity of a cultural group is altered by developmental changes in time keeping and related objective, scientific temporalities.Three modes of temporality, objective, narrative, and transcendental, congruent with different kinds of brain processes, are common throughout our planet. Objective temporality tends to alter and replace traditional (...) narrative and transcendental (spiritual) time, timing, and tempos. Objective temporality is concerned with what is transitory, modern and “progressive”. Objective time is not a traditional form of cultural time; it is a derived Westernized scientific imposition, rather than any cultural formation. This essay develops a new conception of how semiosis occurs. All information is essentially rhythmic, transduced through sensory systems as signals in a space-time domain, but deposited for use into a spectral thermodynamic domain in the human cortex.A “chronemic” perspective, (temporality as it is based in semiotic processes related to human communication) is assumed throughout. Such a perspective appears to be somewhat novel in both communication and semiotic studies. (shrink)

As soon as 'modernity' was defined as a particular way of con ceiving of time, the questions of tempo rality came to be situated at the heart of the ongoing debate regarding the legitimacy or illegitimacy of the 'modern age'. This has, in turn, readily led to a no less passionate search for the assessment of modernity's foundations which are thought to rest in its typical sense of experiencing temporality. This polemic instance, however, involves polarized perspectives and the consequent risk, (...) always present in dichotomous approaches, of oversimplifying the concepts at stake and smoothing over the intricacies of their history and meaning. Does there really exist something like a ' time of modernity'? This is the central question that the present article examines. 1 Key Words: evolution • modemity • philosophy of history • time irreversibility. (shrink)

Nothing seems more possible to me than that people some day will come to the definite opinion that there is no copy in the… nervous system which corresponds to a particular thought, or a particular idea, or, memory.WittgensteinIn a recent essay it was emphasized that brain and mind appear to the mind as complementary and reciprocally recursive domains of a hermeneutic circle (Fischer, 1987). An outstanding and not yet recognized feature of this hermeneutic circle is that interpretation within this circle (...) is not rule-governed and hence appears self-organized: individual features of the world (or the brain) become intelligible in terms of the whole context (of the mind)… while the entire context becomes intelligible through individual features (or brain functions). How, or from where then is significance arising? (shrink)
