John Martin Fischer and Benjamin Mitchell-Yellin have a new book out entitled, Near-Death Experiences Understanding Visions of the Afterlife. While free will is not the focus of the book, Fishcer and Mitchell-Yellin address a number of issues that will be of interest to readers of this blog. Here is the... Continue reading

I am preparing for a new course this semester on philosophy and cognitive science. In the third and final part of the class, we are going to read and discuss Moral Machines: Teaching Robots Right from Wrong by Wendell Wallach and Colin Allen (OUP 2009). Needless to say, I am... Continue reading

I have always been impressed with how bad many (if not most) practitioners of jiu jitsu are at take downs--even when it comes to very basic wrestling take downs such as the double leg or single leg. This is especially true for those who made their way up the ranks... Continue reading

First, I want to wish everyone a happy holiday season--which I hope has been safe and relaxing for the members of our community. Second, I wanted to thank all of the readers who come to this blog for the latest posts and information about experimental philosophy. I started this blog... Continue reading

First, I hope everyone is having a safe and relaxing holiday break. After a semester that brought a gnarly hurricane through Charleston, it has been nice to have such lovely weather for the holidays (the flip side of having to deal with hurricane season). So, I am thankful for that!... Continue reading

The other day I posted a call for curricula (see here). I also think that this commits me to wanting to see more katas. Consider, for instance, affiliations and gyms that have a formal self-defense curriculum (e.g., the Valente Brothers, Royce Gracie, Relson Gracie, etc.). For self-defense, the method of...

For today, I thought I would once again post a pair of opposing instructionals--that is, one showing a technique and the other showing how to defend against the technique. I, for one, always find it useful to look at both a technique and the flip-side! In this case, it will... Continue reading

Here is a quick duo of videos. The first is a sneaky wrist lock set up I have used over the years with varying degrees of the success. The second is a toe hold set up when someone has you in knee shield. I have not tried it out yet,... Continue reading

There are few topics as widely discussed as the meaning (and even the purpose) behind belt promotions (for some earlier grumblings by yours truly, see here and here). Standards vary from gym to gym just as they do from country to country. I have trained with young and hungry competitors... Continue reading

As many of you know, I have been on a leg lock kick for quite some time now. But for all the time I have spent learning different positions (and positional hierarchies), ankle locks, heel hooks, toe holds, and knee bars, I have mostly neglected the calf crush. This is... Continue reading

As many readers know, my health has been deteriorating for some time. While I had a second neck surgery last December to stem the tide of nerve and muscular degeneration, I am still having some problems with my right hand. Needless to say, these can be trying times. I teach... Continue reading

"We must move forward not backward, upward, not forward, and always, twirling, twirling, twirling toward freedom..." For starters, I wanted to thank Michael Bratman for donating his time near the holidays to provide us with some post-Thanksgiving food for philosophical thought. It is always nice to see what some of... Continue reading

Today in class we were discussing a video (below) by Keenan Cornelius because it highlights an important concept--namely, the idea that when we are on bottom, we have multiple levels of defense. Several structures can be put in place to keep one's opponents away using different configurations of one's hands,... Continue reading

Roughly a year ago, I posted some instructionals for the toe hold--a technique I have thought about and worked on quite a bit since then. So, I thought I would post another series of videos to keep my mind fresh with ideas. That said, here they are--from Comprido, Renzo Gracie,... Continue reading

I have discussed so-called "invisible disabilities" on this blog before. In light of the one year anniversary of my most recent neck surgery, I thought I would revisit the issue. More specifically, I want to suggest that several of the disabilities associated with chronic pain put pressure on models of... Continue reading

My good friends are hosting a two week self defense/jiu jitsu/mobility training/strength and conditioning camp being taught by fifth degree black belt Steve Maxwell (Relson Gracie's first black belt). I am still having some problems with my neck (one year post op) plus I don't have $1,200 for the advanced... Continue reading

One of the things than makes jiu jitsu so extraordinary is that practitioners have the ability to meet, learn from, train with, and even compete against their idols and heroes. It's what makes competing at major IBJJF events so amazing. For example, years ago I competed at the Pans as... Continue reading

The morning class has been working on the North/South choke for the past few weeks. Given my fondness of chokes and my fondness of transitioning frequently from side control to North/South, one would think I would already have this particular choke dialed in and yet, I have never quite gotten...

In the last post, I discussed the backstep pass as well as how to use the backstep to set up the knee bar. One thing I have found over the years, however, is that unless you snatch the knee bar really fast when using the backstep, it is hard to... Continue reading

When passing, there is a temptation to become narrowly focused while in top half guard on passing forward with a pressure pass, a knee slide, a staple, etc. While there is nothing wrong with this approach, one should always be open to alternative paths to passing success. One of the... Continue reading

In the wake of multiple remarks Donald Trump made during the recent campaign cycle--remarks that could plausibly be construed as racist and xenophobic (among many other unsavory things)--he was unsurprisingly accused of being a racist and xenophobe. Because he and his supporters deny the charge of racism and xenophobia (often... Continue reading

Dear All, Just a reminder concerning the upcoming schedule for the Featured Author series (see below for details). First, I wanted to once again thank Suzy Killmister for doing a great job stoking the philosophical fires here at Flickers during September. From manipulation and paternalism to addiction and autonomy, she... Continue reading

As someone who trained pretty hard for the better part of ten years with a fused neck (C4-5), I am perhaps uniquely positioned to discuss the pitfalls of stubbornly doing jiu jitsu full-bore when a more intelligent approach was probably called for from the outset. Making matters worse, because I... Continue reading

First, sorry things have been so quiet here as of late. I am teaching a new class this semester (bioethics), I have 120 students, and I submitted a major grant proposal just ahead of being at nearly Ground Zero for Hurricane Matthew here in the low country (I live on... Continue reading

I was just contacted by a psychiatrist in Turkey who wants to translate The Free Will Inventory into Turkish for some research he is planning to conduct. His work is based on this piece he sent me: Weisman de Mamani AG, Gurak K, Maura J, Martinez de Andino A, Weintraub... Continue reading
