Changes

The question of necessary elements is the question of what, if anything, the TSC requires to be theoretically present at the outset, in order for scientific knowledge to get its start[[CiteRef::Barseghyan (2015)|p. 226-233]].

The non-empty [[Scientific Mosaic|mosaic]] theorem asserts that in order for a process of [[Scientific Change|scientific change]] to be possible, the mosaic must necessarily contain at least one element. Scientific change is impossible in an empty mosaic. It can be deduced from the [[The Second Law|second law]], which asserts that in order to become accepted into the mosaic, a [[Theory|theory]] is assessed by the [[Method|method]] actually employed at the time, and the [[The Third Law|third law]], which asserts that a method becomes employed only when it is deducible from other employed methods and accepted theories of the time[[CiteRef::Barseghyan (2015)|p. 226]].

The necessary method theorem asserts that the necessary element required by the non-empty mosaic theorem must be a method. It can be deduced from the second law that in order for a new theory to become accepted, the mosaic must contain at least one employed method. It can be deduced from the third law that in order for a new method to become employed, the mosaic must contain at least one theory and one other employed method. Therefore the initial element could only be a method. Barseghyan [[RefCite::Barseghyan (2015)|p. 230]] suggests that the primordial method might be something extremely general and vague, such as 'accept only the best theories'[[CiteRef::Barseghyan (2015)|p. 228-233]].
