Based on the concept that "the urge to contribute is a human instinct", to seek human ways of living and how they can be put into practice.


We conduct academic and practical research on Homo contribuens, or human beings who are creatures endowed with the urge to contribute as an instinct. We also provide assistance to activities which promote understanding that the urge to contribute is a human instinct.

Homo Contribuens Colloquium

Interested specialists from various fields, such as science, engineering, medicine, philosophy, and religion gathered, and the colloquium was launched in 2003. We hold the colloquium two or three times a year and discuss studies and practices related to “the urge to contribute is a human instinct.”
