As an inevitable product of the development of Internet, the internet of mind is the very essence of the internet of brain, by which direct inter-mind communication could be realized. Accordingly, a number of philosophical significances for the internet of mind may emerge. The complexity of the system formed by the interconnection of brains brings about new intelligences, which may help to solve the problem of understanding other minds in the philosophy of mind, realize the expression and transmission of implicit knowledge, and even change social relationship and lead the mankind towards goodness. At the same time, the internet of mind can also lead to some new philosophical issues—Is the “other mind” understood by the technical means the “carrier” or the “self” of the mind? How to protect the privacy of the mind when it is completely penetrated? Whether or not will it bring new inequality to human beings in the process of connecting to the internet of mind? How to solve these philosophical problems will affect the future development of the internet of mind.
