For me there is only the traveling on paths that have heart. There I travel, and the only worthwhile challenge is to traverse its full length. There I travel, looking, looking breathlessly.

Quest of Human 1

With make-believe everywhere, it doesn't matter who you really are.

An insecure, reclusive Earth scientist is almost killed by a Martian assassin with a focal razor. For his survival, and to uncover the problem with the "deviant diggers" on Mars, he must become a brash and promiscuous Martian mining tycoon.

At the beginning of the 22nd century, in a world of chatty machines, pervasive surveillance, immersive virtual/augmented reality, and standardized brain conditioning, many things are not as they appear.










Logic Ref

LogicRef is an online tool for fast reference to basic concepts and skills for critical thinking for Earth humans in the 21st century. This free tool is a compact summary of basic logic. It is readable on desktop displays, laptops, tablets, and mobile phones. This guide is designed for very quick reference, but it can also be useful for introductory learning and comprehensive reviews.




Hike on the Beach

Centroid Online Learning Modules are online, interactive, self-paced instructional units.


This module will introduce you to the classic Design Argument as formulated by William Paley. You will learn that this argument for “intelligent design” has a long history in the Western wisdom tradition. David Hume’s criticisms of this argument are also covered, and the student learns that Hume’s critique falls short of directly addressing the nature of this argument.


Find out why learning is a lot like hiking.





Hike in the Jungle


Centroid Online Learning Modules are online, interactive, self-paced instructional units.


This module builds on the ideas introduced in the Hike on the Beach module. Taken together, these two self-study modules address the main points in the evolution – intelligent design discussion. Although we conclude that both viewpoints do not have equal status as scientific theories, we also identify basic ethical questions, and note alternative ways of understanding the relationship between science and religion.

Perversity of Virtual Violence According to Albert Borgmann

-Joseph K. Corrado


Many video games today enable users to engage in various forms of virtual violence—often displayed in extreme detail under the users’ interactive control. The broad availability of these systems provokes concern about how best to promote the measured development of reason and to protect the ethical innocence of our children and other vulnerable people, without jeopardizing freedom of speech. Albert Borgmann offers a sturdy conceptual framework for understanding the virtual ambiguity and fog of these entertainment devices and for reframing our discourse. Borgmann reveals the perversion of our ambivalence about the ethical squalor and brilliant excitement of virtual violence.

Responsibility and Imagination in the 21st Ceentury

-Joseph K. Corrado

Virtual reality (VR) systems reset the boundaries for activating and guiding our imaginations. So, we consider that VR might offer new insights for balancing our responsibility to promote the measured development of reason and ethical sensibilities in our children with our heritage of free speech. We look first to the insights from reflective VR users. Then we review some recent findings from neuroscience that relate to understanding VR users’ experiences. Next we survey some key concepts that have emerged from recent philosophical reflections on the structure of technical information and hyper reality. We conclude by imagining a couple of promising paths for future exploration.

Christian-Muslim Dialogue: Interreligious Prospects at the Beginning of the 21st Century

-Joseph K. Corrado


At the beginning of the 21st century, of the world’s five great, nduring religions, the two youngest are also the two most dogmatic—the two least likely to be able to conduct a dialogue with genuine and mutual respect. Today, Christianity and Islam are the clearest examples of creedalism—and thereby, the two religious groups least likely to seek or be able to sustain effective discourse that goes beyond mere tolerance. But the press of historical and current geopolitical events provokes especially Christians and Muslims to develop more effective dialogue.

Guy's Box

-Joseph K. Corrado

Abstract —a science fiction short story

When the mon announced wakeup, Guy bounded from bed and remembered first that it was the first day of his first real job. In a blur of excitement, he showered, shaved, dressed while eating a Mama’s Real Breakfast Bun, and folded up his bed. Slowly, with excitement laced with anxiety, Guy walked over to the corner where his box was installed. His hand groping like a suspicious tentacle, he swung out his coaster chair, settled into the chair's warm hug, and put on the glowing halo.

Meeting Doctor Watson

-Joseph K. Corrado

Abstract —a science fiction short story

I'm like this techno-hermit living in a forest cabin far from the madding crowd. Every day I really get off on the quiet and privacy of my secluded living and every day I connect to the cyber sphere for stuff like news, account updates, email, information searches, and socialmedia strolling in Face2U, and stuff like that. So, anyway, my computer and my chainsaw are my main power tools.

Singing in Summers of Distress

-Joseph K. Corrado

Abstract —a science fiction short story

I awoke to Edward Elgar's Pomp and Circumstance—just as I had instructed my jiggy comm to always play for wake-up music on weekends. It made me feel like I was getting to the finish line with a smooth victory march. I sprang from my bed and paced with the music toward my wall comm, imagining that it would deliver a diploma that would qualify me for a jiggy getaway.
