Out of those choices, I'd say I lean toward the humanist approach myself, with a touch of the presentist/progressive.
The catalyst that got me started was actually fantasy, from D&D and movies, and popular culture. The image of the wizard with a sword (Gandalf), or Arthurian knights, D&D styled wizards and warriors, it was all very creative and alluring. This lead me to want to understand more about the weapons and armor that inspired the fiction. The more I learned about what was real, the more interested I became in the human connection as well.
We may fantasize about it, but people actually lived and died by the weapons, armor, skills, and tactics that we study. These centuries of the past are filled with horrific pain and suffering, but also enormous beauty and accomplishment. Our ancestors were very resourceful people, and I think they still have a lot to teach us.
