A call for Philosophy in public schools

Michael Shammas: For a Better Society, Teach Philosophy in High Schools
Michael Shammas' call for philosophy as a requirement in lower education is his argument on why he believes philosophy is necessary for a healthy society and a strong republic; "because the capacity to debate requires the capacity to think." He extols philosophy for encouraging students to "entertain a thought without accepting it" and be open to the "possibility that one is wrong."
He wonders why philosophy is not already standard curriculum, supposing that "perhaps the subject seems too esoteric or pretentious" or that "[it] could encroach on the sort of questions religion purports to answer." I think Shammas is missing two key elements of educational history. The first of these is the Educational Progressive movement, which by the 20th century had already branded rote memorization and repetition as ineffective and potentially damaging to students. Great thinkers like John Locke and John Dewey (among many others) claimed that children learned best by observation and personal experience, a pedagogical theory I absolutely agree with. The problem came about when the Progressives finally had the opportunity to explore their theories, once enacted the grand ideas of experiential learning quickly degraded into repetitive worksheets describing situations and asking how students would react to them. The great thinkers of the movement couldn't imbue all the teachers with the ability or resources to truly teach by doing, and they fell back into old habits with repeatable results. Most teachers cannot or will not teach a subject which has no right answers, and requires students to be comfortable with that.
The second piece of history Shammas leaves out is the No Child Left Behind act, which standardized curriculum and (more importantly) testing throughout the country. The reason philosophy can't be taught is the same reason he believes it will help people learn: there are no right answers. A federal standardized testing authority cannot judge whether a student has made a moral, empirically supported argument or a sloppy claim to genius; they have neither the funding nor the objective viewpoint to accomplish this.
This all leaves out the fact that if a student does not want to learn something, they won't. Attempting to introduce students who may already have dismissed education as impractical to their lives to Nietzsche and Kant is unlikely to derail their plans away from school.
None of this means that the subject is unworthy of public education, or that it's simply impossible to implement, but many other pieces need to fall into place before such a proposal could be appreciated.

Bicycle Trailer

I love to cycle, and i should ride to school more often, especially since its only a few miles away and parking fees are outrageous. The problem has been that as a sculpture student I'm required to bring tools with me to class, and if I want to do homework I have to bring the tools back, the weight of the tools has prohibited me from cycling with them. But that's no longer acceptable, I've committed to riding as much as possible. 
My solution to the cargo problem: trailer.  Sure, there are plenty of trailers available for purchase, but they can be expensive and kind of dorky. Why buy what you can build? This just a simple wheeled platform fitted to carry my largest toolbox and maybe a little extra.
I started with a piece of electrical conduit, which I bent into a rectangle with rounded ends.

I did this with a simple conduit bender, available at most hardware stores. After the bending I just trimmed the extra piece and welded the ends together.

The frame fits the toolbox just right, so next I bent each end upward to make a cradle.

I did this with the conduit bender again, but since the sides are all connected I had to do each side incrementally, bending one side slightly end then the other slightly more. Once that was done I cut 1/4" bar into sections and welded then across the two sides. I will use bungee cords to secure the box while traveling.

The platform is now done and ready for wheels and a hitch.

Pulley Penicillin

To finish the pulley the last thing it needed was a hub suitable for the 3/4" axle, thankfully I found inexpensive 3/4" collars at Ace Hardware. After centering the collar to the balance point I found previously, all it needed was to be welded.

Not my best weld ever, but it's strong, on center, balanced, and these welds are on the backside so not visible. Overall win.

More work on the motorized bicycle coming soon.

New motorcycle project

This is an early 1980s Suzuki GS850 I was able to pick up for a song. It had a blown head gasket, broken clutch cable, and broken exhaust bolt. But it runs and has a lovely power band, and good sound from the 4 into 1 exhaust (and I believe that's a Kerker muffler), even the tires are in good shape. Shown here with clubman bars already installed and its new fiberglass seat resting peacefully.

Pulley Fever II

Previously on Conjectural Technologies...
I cut a single two-groove pulley in half, making two pulleys.
And now the continuation...
Because this was a harmonic balancer the hub was pressed in with a rubber ring between it and the pulley, knocking it out with a sledge was easy.

Then I traced the core's outside diameter onto steel.

Which I cut out and welded into the pulley.

Now to find the center of my new pulley, I clamped a nail in the vise (checking that it was 90° straight up), and placed the pulley over it, adjusting it by hand at first and then tapping it with a small piece of steel bar until it balanced on the nail.

I eyeballed the pulley as being level, as close as I could get it, then hit it with a hammer so the nail underneath would leave a mark, like a center punch.

This is definitely a primitive way to do this, using appropriate tools it could be achieved with less work and greater accuracy, but I'm working with what I've got.
Next up use to put a 3/4" hub in the center for the axle.

Pulley fever

I need a large pulley for the transmission on the motorized bike, but they're hard to find, and why buy what you could build?
I took the crank pulley from one of my spare Nissan Z-car motors.

But it's very heavy cast steel and has two grooves when I only need one. So I used a DeWalt angle grinder with a cut-off wheel slipped into the small gap between the pulleys to separate them.

It took a while, and because the cut was so deep and narrow the wheel had almost no room to move or tweak.

Now I have two pulley rings, next I have to make one of them mate to the axle of the bike.
