Different Roots of Human Intentionality in Mammalian Mentality

Five mental components of human intentionality are distinguished and related to different properties of mammalian orientation. It is proposed that, in the course of evolution, these old properties became integrated and thereby allowed for the development of a new quality: human orientation. The existence of more than 4,000 mammal species with their various forms and levels of mental organization, offering a panorama of different combinations of differently developed components of mentality, provide ample opportunities for comparative studies. The difficulties in assessing specific types are outlined, drawing on over 40 years of observation. Based on this knowledge, an argument is made for the importance of staying in contact with the empirical objects and of considering their ontological status when rising the standards of precision of formal analysis.
