By using modern imaging technologies, Patrick Colonel Suppes did experiments on the brain＇s cognitive activities. Despite great significance, his experiments have been literally ignored. The technological foundation of Suppes＇s experiments is the mature application of four types of imaging technology on brain, including EEG, MEG, PET and fMRI~ the philosophical foundation is the similarity of technological image, which image shapes; and the ethical foundation relies on the probabilistic similarity of is the participants＇ voluntariness. They work together to form the external and internal foundations. Since Suppes＇s experiments pose challenges to the distinction between object and concept in the philosophical system, particularly the basic distinction between object intentionality and concept intentionality, they must be confronted in the scientific philosophy of phenomenology.
