Mona Hatoum's "+ and –" (1994) is a minimalist installation consisting of two neon signs displaying a plus symbol and a minus symbol, exploring themes of duality, opposition, and the binary logic that structures meaning and systems of control. The work's stark visual simplicity belies its conceptual complexity, inviting viewers to contemplate how polarities organize human experience and language. Through this deceptively basic presentation, Hatoum engages with ideas about power, exclusion, and the arbitrary nature of categorical distinctions.
