But my issue is, what exactly is wrong with being completely objective?
I think you would have to be a robot or something similar for that to be physically possible...
But the question still stands.
What is wrong with wanting only facts and evidence for things?
You are correct that for a fact only view, you can only acknowledge the robotic, being forced, cause and effect. When you introduce freedom in your view of things, then as by logic, subjectivity is the only way to reach a conclusion about what the agency of a decision is. But also the fact category is expanded when freedom is introduced to your view of things, because the decisions, the result of the decisions, and the available alternatives are still matters of fact.
Basically science is now limited to only describe things in terms of being forced, cause and effect. Statistics and such look to be able to describe freedom as well, but statistics is said to be based on chaotically distributed variables. Like in a computer there is a register of aribitrary numbers, which numbers are used to simulate freedom. When the computer pops out number 3 one time and number 8 the next time, then it looks like the computer is choosing things, while actually it is just reading the next number on a list of aribitrary numbers. According to statistical theory the chaos of numbers on the list, is similar to the chaos of variables in nature.
Describing freedom mathematically is a complicated issue. It requires that objects are described as consisting of the laws of nature. That means objects, such as stones, are computers, the objects compute information. As laws unto themselves the objects then have anticipation in regards to the future, and retardation in regards to the past. You should just consider this in terms of that you can describe the object at present with mathematics, and that the object has these add-ons of retardation and anticipation coming from the present, which add ons can also be described with mathematics. Mathematically the anticipation is simply t+1, time +1, time +2 etc. and there are associate alternative potentials to t+1, like mass potential 2 or potential 3.
edit: to be precise the exact reason why facts cannot apply to the agency of a decision is because facts work by being forced, cause and effect. The actual moon is the cause, and the book about the moon containing the facts about it, is in essence the forced effect of that cause.
But the agency of a decision is free per definition, because it chooses. To then regard it as a matter of fact what the agency of a decision is, is to impose the logic of being forced unto the agency of a decision. It is saying freedom = force, which is a logical error.
