Based on historical documents, it is possible that “Dr. Fisher” refers to Dr. Josephine Fallscheer.
‘Abdu’l‑Bahá refers to His talk at Stanford University, Palo Alto, California, in 1912, which was published in the local newspaper and is also included in the collection of His talks in America, entitled The Promulgation of Universal Peace.
There ‘Abdu’l‑Bahá distinguishes the materialistic and empirical philosophy of the modern West from the standard rationalistic philosophy of the Greeks and Persians, and highlights the difference between theories of the essence of nature and of the origin of man.
