This correlation between rationality and logic is unbreakable in our head. For instance, when somebody claims to be a vegetarian, but continue to eat chicken saying that the birds are stupid, we may notice that his/her position lack logic. Continue reading
P=?NP is a famous problem common for mathematical logic and mathematical theory of computational complexity. Computational complexity theory divides formal problems in different classes according to the function that describes the output of the computational machine for the given formula as an input. There are several classes that are combined into a complex hierarchy which though has blank spaces. Continue reading
The industrialization of agriculture in the name of economic efficiency has increased the food supply, (temporarily) defying Malthusian expectations of global mass starvation, but it has also brought with it a series of unprecedented problems. Accordingly, the philosophical literature on questions relating to the ecology of agriculture has multiplied many times over in the last twenty years. Continue reading
Saul Kripke‘s famous but controversial interpretation of Wittgenstein‘s rule-following considerations ignited an ongoing debate on the normativity of meaning. The idea that meaning has a normative, action-guiding component, i.e. that the meaning of a word Continue reading
Argumentation theory has a long history. In my view, the best way to describe its contemporary developments is by considering various theoretical perspectives and approaches. Now, researchers working in various areas investigate the issues of argument. Among them are philosophers, logicians, psychologists, linguists, political Continue reading
2016 year UNESCO declared the «year of Aristotle». The proposal to celebrate 2400 anniversary of Stagirite was presented by the National Commission for UNESCO of Greece with the approval of the «International Centre for Research Aristotle» of Aristotle University of Thessaloniki.
Based and formed logic of Aristotle, as a way to protect the truth and expose the sophistry is relevant for more than two millennia. Continue reading
