Truth synthesis

The Preface of The Bridge gives the argument in three steps.

1. Religions "began as direct encounters" with the deepest questions.
2. Over centuries the insights "fractured into doctrines, symbols, and institutions." The truths remained, but in pieces.
3. The task now is "not to replace existing religions or ask anyone to abandon their faith. It is to connect the dots between them."

Chapter 11 describes spiritual traditions as "various paths up the same mountain." Chapter 27 names teachers from many traditions, among them Jesus, the Buddha, Krishna, Laozi, Rumi, and Muhammad. It describes them as graduates of the same school who stayed on to teach, and says they "are not here to be worshipped."

The text also sets a limit. Chapter 8 states that "any theology that demands the destruction of harmless love or self-respect fails the deeper test of truth." Synthesis, in other words, does not mean accepting every teaching of every tradition.

The idea has a long history.

• Perennial philosophy. The phrase goes back to the sixteenth-century scholar Agostino Steuco. Aldous Huxley gave it its modern meaning: a common core of insight beneath the surface differences of the world's religions.^[2]
• The study of religious experience. William James argued that mystical states across cultures share recognizable features.^[3] See Spinoza, Leibniz, and William James.
• Religious pluralism. John Hick proposed that the major faiths are different human responses to one ultimate reality.^[4]

The strongest objection is that the traditions do not in fact say the same thing. Nirvana, union with God, and liberation of the self are different goals, and the traditions that teach them have said so. The scholar Steven Katz argued further that there is no experience prior to interpretation: a Buddhist and a Christian mystic do not have one experience described two ways, but two different experiences.^[5]

A second objection concerns selection. Any synthesis must decide which teachings are core and which are distortion. The standard used to decide comes from the synthesizer, not from the traditions.
