How to Calculate a Chart in Book One

In episode 386 Chris Brennan addresses a controversial lecture that was recently given by Deborah Holding where she denied the historical existence of the whole sign house system in ancient astrology. Holding claims that whole sign houses did not exist in ancient astrology, and that the concept was only invented in the 1990s by Robert Hand and Robert Schmidt of Project Hindsight. Chris sets out to present evidence that contradicts Holding's claims, demonstrating that there is ample evidence for the existence of whole sign houses in ancient astrology, and to provide a commentary on the distortions and misrepresentations made in her lecture. During the course of the commentary Chris emphasizes the importance of separating the historical debate from the current practice of astrology, and criticizes Holding for denying the historical existence of whole sign houses based on personal preferences rather than objective evidence. Chris also discusses the concept of whole sign house denialism, which is the attempt to deny the existence of whole sign houses in ancient astrology and dismiss or suppress any historical evidence that it existed, as well why it is important to address false claims in order to set the historical record straight.
