Dennett’s first book, Content and Consciousness was published in 1969. Sixteen other books and numerous papers adapted and extended its thesis – that intentionality can be ascribed, along a spectrum with no clear dividing line, impartially to minds, human brains, bees, computers, thermostats: it is a functional relation between object and environment. As to exactly when, in evolutionary or personal history, conscious intentionality arose, “don’t ask,” he said. https://www.theguardian.com/books/2024/apr/21/daniel-dennett-obituary
