If thoughts shape our actions and our actions shape the world, then what shapes our thoughts? What makes us act?
Emotions? Drives? Parenting? Conditioning? Philosophy? Theology? Different for everyone? The same for everyone? Who knows? All of these? Dunno?!.
To me both environment and political theory (aka what we think about ourselves, each other and the world) are greatly interwoven in all spheres of our lives and touch on matters great and small. Not only do I find this truly fascinating, but its depth and impact to me comprise the core of human existence, struggle and potential.
