Aristotelian predicables, universality and realism: the logic of comparison in topics as denying the view that Aristotle was a realist

Aristotle is reportedly held to have been a Moderate Realist in that he would maintain that a concept derives from an act of grasping a mind-independent universal object that exists somehow inside of the many different things which the concept is predicated of. As far as a universal is independent of mind, it would stand for the proper object of a concept that subsumes a given number of things as its own instantiations. But we claim that Aristotle rejected such a view and instead did perceive and comprehend universality as a feature of thought rather than as a feature of reality in its own right. As showed in the chapters of Topics regarding the so-called logic of comparison (with the support of Albert the Great’s commentary), each predicate can be more or less consistent with the attribute of the subject of which it may be predicated. Both essential and accidental attributes assume a definite degree of being related to the degree of belonging to substance. Unlike particular things, the universality of a concept is to be understood always in comparison with another concept according to a hierarchy of predicates in terms of universality degree arranged by comparative terms such as ‘more’, ‘less’, and ‘likewise’. What is really mind-independent are the truth conditions which make a universal true when exclusively referring to a set of things identically meant by the same predicate whose universality is given by the place occupied in the hierarchy of predicates.

The future imagined: Exploring fiction as a means of reflecting on today’s Grand Societal Challenges and tomorrow’s options

European science policy (so-called Horizon 2020) is guided by Grand Societal Challenges (GSCs) with the explicit aim of shaping the future. In this paper we propose an innovative approach to the analysis and critique of Europe’s GSCs. The aim is to explore how speculative and creative fiction offer ways of embodying, telling, imagining, and symbolising ‘futures’, that can provide alternative frames and understandings to enrich the grand challenges of the 21st century, and the related rationale and agendas for ERA and H2020. We identify six ways in which filmic and literary representations can be considered creative foresight methods (i.e. through: creative input, detail, warning, reflection, critique, involvement) and can provide alternative perspectives on these central challenges, and warning signals for the science policy they inform. The inquiry involved the selection of 64 novels and movies engaging with notions of the future, produced over the last 150 years. Content analysis based on a standardised matrix of major themes and sub-domains, allows to build a hierarchy of themes and to identify major patterns of long-lasting concerns about humanity’s future. The study highlights how fiction sees oppression, inequality and a range of ethical issues linked to human and nature’s dignity as central to, and inseparable from innovation, technology and science. It concludes identifying warning signals in four major domains, arguing that these signals are compelling, and ought to be heard, not least because elements of such future have already escaped the imaginary world to make part of today’s experience. It identifies areas poorly defined or absent from Europe's science agenda, and argues for the need to increase research into human, social, political and cultural processes involved in techno-science endeavours.
