We live in complex societies facing numerous challenges, such as the erosion of social cohesion, widening wealth and income gaps, unsustainable development and climate change, increasing demands on health care systems, deficiencies in education and persistent inequalities. The Centre for Knowledge and Society (CEKAS) aims to address problems of this type by applying philosophical tools and notions drawn from all the sub-disciplines of theoretical and practical philosophy in collaboration with specialists from other disciplines. Specifically, CEKAS aims to improve understanding of societal challenges and to recommend and develop interventions that have societal impact. This requires a multi-disciplinary effort, requiring collaborations with both academic non-philosophers and non-academic stakeholders.
