Progressivism is premised upon the idea that it is a living, breathing organism that changes with the times and that these changes mark the gradual improvement of human development of thought, and since everything is a continual work-in-progress, updates are being constantly stacked on top of previous iterations where the latest version is better off the merits of it building upon the previous one which is outdated the moment the next update is ready for upload, or dissemination in the human sphere.
