History
As of 1910, ISVW has been a centre for the in-depth exploration of philosophies of life and worldviews, with personal development, emancipation and critical thinking at its heart. Both then and now, we strive for an international exchange of ideas and a society in which philosophy and ethical awareness play a role.
