This thesis presents the first scholarly attempt to provide a systematic study—by way of rational reconstruction—of Avicenna’s philosophical analysis of knowledge. The analysis is centred on the well-known but ill-researched epistemic notions of apprehension (taṣawwur) and judgement (taṣdīq) that Avicenna consistently claims to be the necessary and sufficient conditions for anyone to be regarded as having knowledge. The study, however, begins with an account of Avicenna’s philosophical programme and its primary philosophical assumption, namely, his metaphysical realism. I argue that this assumption is the most fundamental principle from which emerge all strands of his thought and by which all his philosophical views are unified into a single philosophical system. Thus, I argue that it is with a clear view of his metaphysical realism and the broader philosophical programme which grows out of it that we can make fully sense of Avicenna’s philosophical analysis of knowledge and his epistemology in general. Bearing this in mind, I proceed with a systematic and rational reconstruction of Avicenna’s epistemic concepts of apprehension and judgement and followed then by his conception of truth (al-haq), which is implicit in his epistemic notion of judgement. Given that for Avicenna, as we shall see, it is only true judgement that can be counted as knowledge. Furthermore, a truly realist philosophical account of knowledge, or epistemology in general, must make a contact with psychology. I provide therefore an account of Avicenna’s psychological explanations of all the mental processes that involved in knowing. This includes his account of epistemic faculties—such as consciousness, sense perception, mind, and reason—and all the kinds of knowledge that these faculties yield to human beings. With the completion of my attempt at a systematic and rational reconstruction of Avicenna’s philosophical account of knowledge in terms of the epistemic notions of apprehension, judgement, and truth, I close the study by way of summarising his analysis of knowledge in modern form. And, lastly, I suggest that given the fact that this thesis is the first scholarly attempt at a systematic study of Avicenna’s philosophical analysis of knowledge, I should like it to be seen as a prolegomenon to develop rigorous arguments for his analysis as the basis for a tenable alternative to the traditional account of knowledge.

The wave of knowledge loss that organisations are facing on account of layoffs, retirements, staff turnover and mergers gave rise to this research. The main research aim was to identify the organisational and behavioural factors that could enhance or impede tacit knowledge retention. A multidisciplinary approach focusing on knowledge management, organisational behaviour and organisational development was followed. The nature of knowledge in organisations was explored by following a contextualised theorybuilding process, focusing on epistemology, and the appearance and application of knowledge. Knowledge in the context of this research is the knowledge and experience that reside in the minds of people. It is not easily documented, and is referred to as tacit knowing. A theoretical model was developed that revealed the factors that could influence tacit knowledge retention. The model focused on human input factors taking into account knowledge loss risks, strategic risks and behavioural threats that could cause knowledge loss.The main purpose of the empirical research was to operationalise the theoretically derived knowledge retention constructs, determine statistically the enhancing and impeding factors that influence knowledge retention and develop a structural equation model to verify the theoretical model. A quantitative empirical research paradigm using the survey method was followed. A questionnaire was compiled, and a survey conducted in the water supply industry. The principal component factor analysis postulated nine factors. A composite factor, knowledge retention, as the dependent variable was compiled. The questionnaire was found to be reliable, with a Cronbach alpha coefficient of .975. A structural equation model development strategy produced a new best-fitting knowledge retention model based on the new constructs postulated in the factor analysis. The model indicated that there is a direct causal relationship between strategy implementation and knowledge retention and between knowledge behaviours and knowledge retention. The regression analysis showed that most of the intercorrelations are significant, thus confirming the theory. The research contributed towards a comprehensive understanding of the factors that influence tacit knowledge retention. The questionnaire and the new knowledge retention model could assist organisations in determining the extent to which knowledge is retained and where to focus in developing and implementing a knowledge retention strategy. The study encourages practitioners to take cognisance of the fact that organisations are different and that the enhacing and impeding factors of knowledge retention are to be considered. / Information Science / D.

This dissertation studies the intersection of knowledge, culture, and power in contested coastal and estuarine space in eighteenth-century northeastern North America. It examines the interdependence of vernacular pilot knowledge and directed hydrographic survey, their integration into practices of warfare and governance, and roles in assimilating American space to metropolitan scientific and aesthetic discourses. It argues that the embodied skill and local knowledge of colonial and Aboriginal peoples served vital and underappreciated roles in Great Britain’s extension of overseas activity and interest, of maritime empire. It examines the maritimicity of empire: empire as adaptation to marine environments through which it conducted political influence and commercial endeavour. The materiality of maritime empire—its reliance on patterns of wind and current, on climate and weather, on local relations of sea to land, on proximity of spaces and resources to oceanic circuits—framed and delimited transnational flows of commerce and state power. This was especially so in coastal and riverine littoral spaces of northeastern North America. In this local Atlantic, pilot knowledge—and its systematization in marine cartography through hydrographic survey—adapted processes of empire to the materiality of the maritime, and especially to the littoral, environment. Eighteenth-century British state agents acting in northeastern North America—in Mi’kmaqi/Acadia/Nova Scotia, Newfoundland and Labrador, Quebec, and New England—developed new means of adapting this knowledge to the tasks of maritime empire, creating potent tools with which to extend Britain’s imperial power and influence amphibiously in the eighteenth and nineteenth centuries. If the open Atlantic became a maritime highway in this period, traversed with increasing frequency and ease, inshore waters remained dangerous bypaths, subject to geographical and meteorological hazards that checked overseas commercial exchange and the military and administrative processes that constituted maritime empire. While patterns of oceanic circulation permitted extension of these activities globally in the early modern period, the complex interrelation of marine and terrestrial geography and climate in coastal and estuarine waters long set limits on maritime imperial activity. This dissertation examines the nature of these limits, and the means that eighteenth-century British commercial and imperial actors developed to overcome them.
