If personal identity consists in non-branching psychological continuity, then the sharp breaks in psychological connectedness characteristic of Multiple Personality Disorder implicitly commit psychological continuity theories to a metaphysically extravagant reification of alters. Animalist theories of personal identity avoid the reification of alternate personalities by interpreting multiple personality as a failure to integrate alternative autobiographical memory schemata. In the normal case, autobiographical memory cross-classifies a human life, and in so doing provides access to a variety of interpretative frameworks with their associated (...) clusters of general event memory and episodic memory. Multiples exhibit erratic behavior because they cannot access reliably the intersecting autobiographical memory schemata that permit graceful transitions between social roles, behavioral repertoire and emotional dispositions. Selves, in both normal and certain pathological cases, are best understood as semi-fictional narratives created by human animals to serve their social, emotional and physical needs. (shrink)

In this paper I will analyse the relationship between metaphor and imagination. This issue has been recently studied by cognitive linguists who appreciate its importance, while other semantic perspectives neglect it. I will analyse the thesis which affirms that metaphors are based on cognitive components which are not logical-propositional but imaginative: the “image schemata” are recurrent models of corporeal experiences, centres of knowledge organization which structure – in a non-propositional form – an amount of salient information. This information emerges from (...) the sensorimotor activities such as: manipulation of objects, spatial orientation and focusing perceptive attention on different goals. According to this theory, imagination is the drive of the entire cognitive experience and, through metaphorical projection, it activates and coordinates the schemata from which the very linguistic activity originates. Starting with empirical studies about the cognitive and neurobiological plausibility of image schemata, I will assert the function of imagination as the trait d’union between experience and cognitive use of the metaphor, through the use of sensory and synesthetic metaphors as mediators among perceptive, physical and linguistic dimensions. I hope future research will concentrate on the relationship between synesthesia and image schemata because of their strong connection with human perceptive, cognitive and neural structures. (shrink)
