“It is more of a philosophical text that touches several issues that daily confront people involved in artificial intelligence, natural language understanding, and fuzzy modeling. Due to its thought-provoking nature, sometimes re-reading is necessary in order to fully understand the author’s thoughts. Reading this book may raise feelings of a disparate nature: excitement, perplexity, enlightenment, and incompleteness. In all cases, the ingenuous will surely find stimuli for further thinking and meditation.” (Corrado Mencar, Computing Reviews, April, 2018)
