"Descartes's Arguments for Universal Doubt and the "Cogito" Argument (An Outline of Meditations 1,2) The argument for universal doubt: A. The dream argument: 1. I often have perceptions very much like the ones I usually have in sensation while I am dreaming. 2. There are no definite signs to distinguish dream experience from waking experience. therefore,"

"Contemporary philosophical discussions of the imagination have been primarily focused on three sets of topics. Work in philosophy of mind and philosophy of psychology has explored a cluster of issues concerning the phenomenology and cognitive architecture of imagination, examining the ways that imagination differs from and resembles other mental states both phenomenologically and functionally, and investigating the roles that imagination may play in the understanding of self and others, and in the representation of past, future and counterfactual scenarios. Work in aesthetics has focused on issues related to imaginative engagement with fictional characters and events, identifying and offering resolutions to a number of (apparent) paradoxes. And work in modal epistemology has focused on the extent to which imaginability-and its cousin conceivability-can serve as guides to possibility."

"LAST week, Johnson took a look at some of the advantages of bilingualism. These include better performance at tasks involving "executive function" (which involve the brain's ability to plan and prioritise), better defence against dementia in old age and-the obvious-the ability to speak a second language. One purported advantage was not mentioned, though. Many multilinguals report different personalities, or even different worldviews, when they speak their different languages."
