Maria Montessori’s vision of human development across the Four Planes of Education remains one of the most integrated developmental theories in modern pedagogy. The Fourth Plane (ages 18–24)—the formation of the adult personality, moral purpose, and spiritual journey—remains the least articulated, researched, and practiced dimension of Montessori education. At a time when adolescent and higher education are increasingly fragmented, formalized, and disconnected, this work is urgent.

The Keepers of Alexandria: In the Fullness of Time responds directly to this unfinished work by offering a developmental, interdisciplinary, and classical framework that unifies the Four Planes in both theory and practice.


  • Montessori middle school & adolescent teachers
  • Montessori teacher educators
  • School leaders and curriculum designers
  • Higher education faculty & researchers
  • Educators engaged in classical, humanistic, or peace education

Why Attend


✔ Deepen understanding of the Second → Third → Fourth Plane continuum in the context of the Four Planes Theory
✔ Experience a living demonstration of classical Montessori humanities
✔ Explore Montessori’s unfinished work in for the 18–24 age group
✔ Engage with internationally respected Montessori scholars
✔ Explore the future design of advanced Montessori education

Questions We Will Explore

How does the Second Plane prepare the foundation for adulthood? How does adolescent identity mature into responsibility? What might Montessori education look like at the Fourth Plane?

Why This Matters

* The Second Plane awakens imagination and intellect. *The Third Plane tests identity through experience and responsibility. *The Fourth Plane brings the adult personality to maturity in thought, culture, and purpose. Education, in the fullness of time, prepares the human being not simply to succeed — but to contribute to civilization.

About Presenters

Kathleen Allen, Ph.D.

Kathleen Allen is AMI Elementary trained and taught for forty-eight years prior to her retirement in 2021. She holds a PhD in Humanities and Culture
from Union Institute & University.

to 6, 6 to 12, and 12-15 Montessori programs. Gerry was a co-developer with David Kahn of the NAMTA Centenary Exhibit, A Montessori Journey:1907- 2007.
The latter exhibit toured seven cities in North America and is now permanently housed at The Montessori Center of Minnesota in St. Paul.

David Kahn

David Kahn has become de facto the legacy documenter of the AMI world, through his 50-year sole editorship for the North American Montessori Teachers’ Association and the last six years with the Association Montessori Internationale Journal. David has served as a director for various non-profit Montessori management organizations over the last 60 years. He has 17 years of Montessori teaching
experience, 12 of them as teaching principal at Ruffing Montessori School. David founded the Hershey Montessori in 2000 School’s Adolescent Community, an internationally acclaimed Montessori farm school model for adolescent education. He served as founding director emeritus of Montessori High School at University Circle, Cleveland, Ohio. The original AMI Montessori Orientation to Adolescent Studies initially guided and developed teachers who worked with students ages 12–18, with David’s leadership as a main contribution. David holds a BA in fine arts and Great Books from the University of Notre Dame as well as the AMI Montessori elementary diploma from Bergamo, Italy. This
conference is the occasion for a collaboration with Baiba Krummins Grazzini spanning her shared roots from that of Camillo Grazzini. David has utilized his film and writing skills to create the largest global Montessori media history initiative, documenting Montessori innovation and implementation in both the public and private sectors through video and publications. He has created two major museum exhibits that have accented the social and ecological directions of the Montessori movement. The high school reflects Mr Kahn’s awareness in the context of a general education, then with specific knowledge and skills through psycho-disciplines. Regional high schools focus on both farm and urban areas with an emphasis on practical arts and social contribution that defines the dignity of responsibility. He currently directs Montessori global classical studies by integrating the Syntopicon and Great Books—originated by Mortimer Adler and Robert Maynard Hutchins at the University of Chicago Committee on Social Thought. He is about to present a proposal regarding Montessori Great Books seminars to be reviewed with AMI and Montessori-Pierson Books. David also helps advance the Montessori Institute for the Science of Peace with international implementation under the discretion of the Philippines, Abba Orchard Schools and the Barrameda Family.
