Lovingly prepared by Joshua Marker along with a devoted team of volunteers, this commemorative publication of PiHKAL: A Chemical Love Story and TiHKAL: The Continuation features the original texts enhanced with complete errata, new essays, anecdotes, and reminiscences by numerous colleagues, previously unpublished photographs, and original art. PiHKAL is the fictionalized autobiographical account of Sasha and Ann Shulgin's research and romance, exploring altered state experiences in the context of intimacy. It describes a wide variety of phenethylamines, their dosage, and their effects. The second volume, TiHKAL, uses the same format as its predecessor to describe the effects of a range of tryptamines, and continues the Shulgin's chemical love story. It also includes appendices that relate to cactus alkaloids, natural beta-carbolines, and drug law. In this edition, each book has been split into two paperback volumes to make a collection of four, housed in a commemorative slipcase set.

The Commemorative Edition of PiHKAL and TIHKAL, a four volume set complete with 200 original photographs, art, poetry, and numerous anecdotes and reminiscences by colleagues and close friends, chronicles the explorations of psychopharmacologist Alexander Shulgin and his wife Ann Shulgin into the families of psychoactive compounds known as phenethylamines and tryptamines.

Book I: The Story Continues This is the continuation of the love story from PIHKAL: A Chemical Love Story with a blend of travel, botanical facts, scientific speculation, psychological and political commentary. Book II: The Chemistry Continues Describes in detail a wealth of tryptamines in the same format as Book II of PIHKAL, plus appendices presenting topics such as cactus alkaloids, natural beta-carbolines, current drug law, and all known tryptamines (from the literature) that might be psychedelic.

Singularity Hypotheses: A Scientific and Philosophical Assessment offers authoritative, jargon-free essays and critical commentaries on accelerating technological progress and the notion of technological singularity. It focuses on conjectures about the intelligence explosion, transhumanism, and whole brain emulation. Recent years have seen a plethora of forecasts about the profound, disruptive impact that is likely to result from further progress in these areas. Many commentators however doubt the scientific rigor of these forecasts, rejecting them as speculative and unfounded. We therefore invited prominent computer scientists, physicists, philosophers, biologists, economists and other thinkers to assess the singularity hypotheses. Their contributions go beyond speculation, providing deep insights into the main issues and a balanced picture of the debate.
