"A student well versed in even one technique will naturally see corresponding points in other techniques. A upper level punch, a lower punch, a front punch and a reverse punch are all essentially the same. Looking over thirty-odd kata, he should be able to see that they are essentially variations on just a handful."

How could a readiness for war in time of peace be safely prohibited, unless we could prohibit, in like manner, the preparations and establishments of every hostile nation? The means of security can only be regulated by the means and the danger of attack. They will, in fact, be ever determined by these rules, and by no others . . . . If one nation maintains constantly a disciplined army, ready for service of ambition or revenge, it obliges the most pacific nations who may be within the reach of its enterprises to take corresponding precautions.
