Abstract
This paper explores parallels between the Liar and various aspects of philosophical reasoning. It begins by analyzing the liar sentence, “This sentence is false”, by highlighting its self-referential nature and alternating truth values. The paper then draws connections between the Liar and Hegel’s speculative sentence, proposing it as a ‘quasi-speculative sentence’ that mirrors dialectical reasoning. Subsequent sections examine the logocentric predicament, Zeno’s paradox, the realism vs. anti-realism debate, and determinism, illustrating how they embody similar self-negating structures. The analysis sheds light on the underlying structure of our philosophical reasoning.
