How the Drug War limits our understanding of Immanuel Kant

an open letter to Dr. V.A. Gijsbers of Leiden University

by Brian Ballard Quass, the Drug War Philosopher

March 6, 2024



Hello, Doctor Gijsbers and greetings from Virginia, USA.

Thanks for the excellent videos on Immanuel Kant 1 and his Critique of Pure Reason2. They are helping me finally begin to understand this book, which I only dimly comprehended (if at all) in university. What follows are some no doubt controversial thoughts about Kant and his discussion of the noumenal world. I am hoping that you will find time to read them. If so, I would be delighted to hear your thoughts. Please understand, however, that any criticisms below are directed toward philosophy as a field and not by any means toward yourself in particular.

Thanks again!

I am a 65-year-old philosophy buff from the states who has written hundreds of essays regarding the philosophy of the War on Drugs and the attitudes that it represents. I believe that the Drug War has censored academia and in ways that most academics neither acknowledge or see. I think that the study of Kant is a case in point. For I would claim that the subject of metaphysics cannot be exhaustively discussed (especially post-Kant) without a discussion of the effects of drugs on the human understanding, especially psychedelics and the various phenethylamines synthesized by chemists like Alexander Shulgin3. These substances, after all, provide many with what they believe to be a firsthand experience of the noumenal world, a belief maintained both by tribal peoples and the majority of psychedelic users in the modern west. Nor is the interest in such brave new worlds of experience limited to tribal peoples and hippies. William James himself believed that we should study such worlds when he wrote the following in "The Varieties of Religious Experience":

"No account of the universe in its totality can be final which leaves these other forms of consciousness quite disregarded"4.


Unfortunately, the Drug War forces us to disregard such forms of consciousness by outlawing the very substances that cause them. But that need not keep us from at least talking about such seemingly noumenal states.

What might the accounts of drug use tell us about the noumenal world? Permit me to give one example from personal experience.

In 2017, I traveled to Arizona to take a "spirit walk" inspired by the consumption of a peyote cactus button. During the "trip," I beheld (with my eyes shut) a neon-green slideshow of Mesoamerican imagery, with stylized depictions of warriors and animals, closely resembling the imagery found on Mayan sculpture, murals, and calendars.

Now, I am not a Mesoamerican scholar, nor was I consciously thinking of Mesoamerican history during this time in my life. So the fact that I should have such an experience should provide fodder for a wide variety of informed speculation about the nature of the noumenal world, especially as this experience occurred in an historically tribal region and using a substance that had a long history of tribal use. At very least, the experience casts doubt on any materialist account of consciousness and suggests (though certainly does not prove) the existence of a sort of panpsychic world in which the natural world participates with human consciousness in passing along culturally specific thoughts, feelings and ideas about the phenomenal world around us.

Unfortunately, the academic world pretends that drugs do not exist, and in this way, they give a monopoly to materialist explanations for experiences of this kind (when they do not ignore such experiences altogether, which is, indeed, the standard materialist MO in these cases). I await the day when academics will realize that educators are not free in the age of a Drug War and that all our supposed knowledge is based on an unacknowledged acceptance of the drug-hating ideas of Mary Baker Eddy: namely, that outlawed drugs can have no positive uses whatsoever and that therefore the effects that they have on the minds of human beings need not be taken into account when considering the truths of philosophy, or of psychology for that matter. Indeed, psychology not only ignores the Drug War but it embraces it every time that it refers to demonized substances for depression as "crutches" and plumps rather for the use of pharmaceuticals that purport to work in a "scientific" (i.e. materialist) fashion, notwithstanding the fact that the latter create lifelong dependency in 1 in 4 American women.

The idea that psychedelic drug users are seeing the noumenal world is supported by the filter theory of consciousness championed by Aldous Huxley, which states that the categories through which we observe phenomena in our sober lives constitute but one of many prisms through which we can see the world, and that psychoactive drugs have the power to open the "doors of perception" to many other aspects of reality5. These other realities are necessarily noumenal insofar as there is no consistency between "trippers" when it comes to the nature of these other worlds, notwithstanding the fact that drug users obtain different experiences from the same substance at the same dose in the same setting, etc., although the Drug Warrior might join the materialist in claiming that such experiences are merely pathological.

I will spare you any further attempts at elucidating my thesis. I hope in this short space, however, I have at least given you some reason to believe that the Drug War is, indeed, censoring academia, and that in so doing, it is limiting the extent to which we can profit from, and perhaps even improve upon, the insights of Kant with respect to our understanding of metaphysics and the perhaps "not so unknowable" nature of the noumenal world.

against the hateful war on US




The U.S. Congress considered the following to be a scientific fact back in 1924: "A person taking narcotics regularly impedes evolutionary progress and tends to degenerate backwards toward the brute." -- Richmond Hobson

When it comes to "drugs," the government plays Polonius to our Ophelia: OPHELIA: I do not know, my lord, what I should think. POLONIUS: Marry, I'll teach you; think yourself a baby!

The term "drugs" is no more objective than the term "scabs." Both are meant to defame the things that they denote.

All drugs have positive uses. It's absurd to prohibit them because one demographic might misuse them.

If drug war logic made sense, we would outlaw endless things in addition to drugs. Because the drug war says that it's all worth it if we can save just one life -- which is generally the life of a white suburban young person, btw.

SWAT raids have increased by 15,000 percent from the late 1970s to today, resulting in 50,000 to 80,000 SWAT raids annually in the US alone. --War On Us

Thomas Szasz was not an extremist when it comes to drugs. The extremists are those who feel that psychiatrists know more about our mind and mood than we do.

If Americans cannot handle the truth about drugs, then there is something wrong with Americans, not with drugs.

Clearly a millennia's worth of positive use of coca by the Peruvian Indians means nothing to the FDA. Proof must show up under a microscope.

We need to start thinking of drug-related deaths like we do about car accidents: They're terrible, and yet they should move us to make driving safer, not to outlaw driving. To think otherwise is to swallow the drug war lie that "drugs" can have no positive uses.

Break the ice with a sledgehammer: place this book on your coffee table.

This book features 150 annotated images, designed to force brainwashed Americans to confront the fact that drug prohibition is wrong. Here is what author Richard Parrish II says of the book's compiler: "The drug prohibition philosopher provides first-hand, principled, persuasive, and insightful arguments against the current drug prohibition regime..."

Diary of a Drug Fiend

This is the only full-cast recording of Aleister Crowley's 1922 classic paeon to common sense. It is the first book -- and so far almost the only book -- to stake out a philosophy of drug use that is compatible with human freedom, one in which we learn to use drugs as wisely as possible for the benefit of humanity. This recording was produced by the Drug War Philosopher and your purchases help support his effort to push back against the tragically counterproductive policy of drug prohibition, in the name of human freedom and of humanity's right to heal.
