The Embassy of the Free Mind is a private non-profit: a museum, a library, a research institute and a living community in the heart of Amsterdam. Rooted in the principle of Ad Fontes (Back to the Source) our mission is to preserve the legacy of ancient wisdom traditions by preserving and sharing the wisdom of the Bibliotheca Philosophica Hermetica.
An investment in the Embassy of the Free Mind is an investment in freedom of thought, and in ensuring that future generations have the knowledge, imagination and independence to think for themselves. Your generosity is what keeps this place alive and its doors open. Every donation, large or small, makes a direct difference.
By remembering the Embassy of the Free Mind in your will, you help ensure that the sources of free thought are preserved, studied and kept open to readers for the generations to come.
A legacy gift, large or small, becomes part of our running institution to preserve the sources for those who come after us. It supports the care of the Bibliotheca Philosophica Hermetica, its accessibility to readers everywhere, and the programme that brings them to life.

The Embassy of the Free Mind houses one of the world’s most remarkable collections of hermetic, mystical, and esoteric knowledge, carefully built over decades and now entrusted to the Embassy of the Free Mind to share with a wide audience.
Caring for this living collection takes ongoing dedication: preserving and digitising its treasures, maintaining the historic building, welcoming visitors, supporting researchers, and creating a vibrant public program that brings people together around the spirit of free thought. This work is made possible in large part through the generous support of individual donors and sponsors who help sustain and grow our mission.

Collection - Help us conserve, digitise, and expand one of the world's most extraordinary archives of hermetic and esoteric wisdom.

Research - Support open access to the BPH for scholars, students, and independent thinkers from around the world.

Sharing - Enable us to share these ideas through exhibitions, events, Academy programmes, publications, and our growing online community.
