Aristides Baltas (Greek: Αριστείδης Μπαλτάς; born 9 February 1943) is a philosopher of science and physicist who served as the Minister of Culture and Sports of Greece and as the Minister of Culture, Education and Religious Affairs in the cabinet of Alexis Tsipras from 27 January 2015 to 4 November 2016.

He is currently the Emeritus Professor of Philosophy of Science at the National Technical University of Athens and President of the Nicos Poulantzas Institute.

[4] Other philosophers studied by Baltas include Ludwig Wittgenstein, Friedrich Nietzsche, Baruch Spinoza, Jacques Derrida, John McDowell, and Walter Benjamin.

[1] In 2002, Baltas was awarded the National Prize for Nonfiction for his book Objects and Aspects of Self (Αντικείμενα και όψεις εαυτού).

Soon after entering office, Baltas stated that beyond the immediate objectives of relieving the humanitarian crisis in Greek schools and resolving the problem of "eternal students" who are forced to suspend their studies in order to find work to sustain themselves, his long-term goals as minister would be to restore the independence of secondary education from higher education, to abolish pan-Hellenic examinations, and to support free access to higher education.
