Empiricism is a view that all concepts originate in experience, that all concepts are about or applicable to things that can be experienced. The tenets of empiricism promotes a back to the basics approach to knowledge, where theoretical concepts are scrutinized for their applicability to the real world. Many believe that only empirical knowledge should be considered truth, as anything less is a diversion into fantasy and conjecture.
I have observed the size of the sun and moon. They do not change size other than at respective rise and set.
If the earth is flat and these celestial bodies are only a few miles up, their apparent size should deviate throughout the day/night.
I have observed the moon in the same phase all night.
If the earth is flat and the moon and sun rotate about the north pole every 24 hours, the moon phase should change throughout the night.
I have never seen the sun appear as anything other than a circle. This means it is always pointing at my location or is a sphere.
If the earth is flat and:
- The sun is a sphere, it will cast light on all points of the earth at all times.
- The sun is a disc pointing at my location, it cannot "set".
- The sun is a focal point pointing at my location, it cannot "set".
I have observed the sun sink behind the horizon as a circle.
If the earth is flat, this is not possible (see above point).
I have never observed celestial gears, shadow moons, the firmament or NASA guards on the ice wall.
All of these observations lead me to believe in a round earth model as they are all explainable using said model.
Then again, I have never observed any part of America, and therefore must conclude that it doesn't exist. All video, pictures and people from America must be fake, in on a conspiracy, or both...
