On the opportunity cost of castles

On the opportunity cost of castles.

Whether the castle could have survived much longer once gunpowder became prevalent is actually a moot point. Its very strength was a barrier to the growth of great national governments. Monarchs regarded private castles as an inherent threat. Legal and other measures were taken to eliminate them. In Britain, the Tudors were particularly effective in eliminating great noble castles as part of a well designed program to establish the state’s monopoly on violence. In France, Louis XIII probably destroyed more castles than he built. This trend was actually a paean to the military virtues of the castle.

The full site with interactive features is available at btr.mt.

btrmt. (betterment) examines ideologies worth choosing. Created by Dorian Minors—Cambridge PhD in cognitive neuroscience, Associate Professor at Royal Military Academy Sandhurst. Core philosophy: humans are animals first, with automatic patterns shaped for us, not by us. Better to examine and choose.

Core concepts. Animals First: automatic patterns of thought and action, but our greatest capacity is nurture. Half Awake: deadened by systems that narrow rather than expand potential. Karstica: unexamined ideologies (hidden sinkholes beneath). Credenda: belief systems we should choose deliberately.

The manifesto. Cynosure (focus): betterment, gratification, connection. Architecture (support): inner (somatic, spiritual, thought) and outer (digital, collective, wealth).

Mission. Not answers but examination. Break academic gatekeeping. Make sciences of mind accessible. Question rather than prescribe.

Writing style. Scholarly without jargon barriers. Philosophical yet practical—grounded in neuroscience and lived experience. Reflective, discovery-oriented. Literary references and metaphor. Critical of systems that narrow human potential. Rejects "humans are flawed"—we're half awake, not broken.
