The purpose of the constitutionalisation of private law is the influence of constitutional norms on private relations. Contrary to traditional views, the guaranteed rights of the constitution are not the only means of defending individuals against the state, but it is necessary to apply and interpret all branches of the legal system in the light of it. Therefore, private rights are also dominated by these rights and people need to set up their own private relationships in the shadow of it. This research intends to examine the theory of the constitutionalisation of private law and its possible acceptance in Iran's law through a descriptive and analytical method. It can briefly be said that the basic rights over the entire legal system, especially indirectly, are superior. Also, despite the lack of a constitutional court in Iran, and the lack of a welcome judicial approach to Constitutionalisation, it should be said that iran private law has the necessary capacities for Constitutionalisation.

This study seeks to identify sustainable competitive advantages of Gorgan VET private institutes. These advantages were identified based on the dimensions of quality, efficiency, customer responsiveness and innovation. The target community, directors and founders of VET private institutes in Gorgan, were 453 people who work in 206 institutes. Random sampling was done by observing the sample by Morgan table 210, respectively. The data gathering tool included information from previous documents and records, and a researcher-made questionnaire to collect experts' comments to identify competitive advantages, as well as another researcher-made questionnaire for obtaining the views of sample individuals to determine the importance and priority of the competitive advantages identified by VET private institutes. The reliability of the questionnaire using Cronbach's alpha coefficient was equal to 968/0. The face and content validity of the questionnaire was evaluated by a group of experts and experts in various disciplines and counselors. Considering the fact that the information was collected from sample people in the form of confirmatory factor analysis, the validity of the questionnaire was confirmed during the tests by the software.

Wittgenstein considered that the notion of a private language rested on two fundamental mistakes: one about the nature of experience, and one about the nature of language. The former is the belief that experience is private; the latter is the belief that words can acquire meaning by ostensive definition. The so-calledp: private language argument" establishes that the speaker of the language would be left with no way to distinguish between seeming right and being right; i.e, nobody other than the speaker could understand it and nothing could be recognized as a word of such a language to refer to a thing. In this paper, we first discuss 243-258 of the Philosophical Investigations in order to find a comprehensive and truthful reading of the argument. Then we present a comparative discussion of some of his commentator's explanations. Our discussion shows that Kenny's reading of Wittgenstein should be seen as the most reliable and coherent readings.
