The Principle of Unity of Nature LawsJustifications and Objections

Abstract

This paper aims to discuss the principle of unity of nature laws in its historical development, from the requirement unified explanation of nature with the Ionic philosophers, to Atomic philosophers, through the unification of sciences and their method's requirement with Descartes, then the attempt to establish a theory of everything with ultimate laws as general rules in the 20^th. and the reduction base to that "unification" from various scientific laws to single ultimate group of laws, express generic facts. and its justifications, which base on the character of unitary science, as a micro reduction on several levels, which express the natural system in science. Also, principle of sufficient reason, that through, the unified nature appears like a sufficient reason to the requirement of ultimate theory, or connect with the law of parsimony, whereas, the unification looks like the goal of the thought requiring the simplicity, or that which base on the axiomatization of science by making it generic cases as fundamental laws and

which the rest of scientific laws are deduced from.

Also, the paper argues the objections which addressed to such "unification", like the restriction of ontological reduction of fulfilment the science requirement, it denies the disciplines of special sciences difference and the natural kinds of their predicates. Addition to, unjustified logical necessitation as a result of axiomatization of science by making it a deductive framework its results confirm with premises, also the problem of induction, which lead to unjustified unified explanation as Hume argued, Furthermore, the incompleteness of our laws and the impossibility of unifying them before identifying all forces and laws governing nature, as suggested by Feynman and Cartwright, although the epistemological obstruction generated from such unity; the excessive generalization, substantializing the ultimate law, in fact the completeness what had been added to the paradigm, careless for the effect of crisis in changing the paradigm; which deny the unification,  that contradiction philosophy of science in 20^th century. Addition to the Laplacian absolute predictability follows the unified theory with its ultimate laws, breaking the Indeterminacy as a basic element of any natural unified theory, and the problems affect its mathematical formulations directed from the Godel's incompleteness theorem. In conclusion, through these critiques we attempt to discuss the epistemological obstructions which prevent any complete formulation to the principle of unity of nature laws.
