August 18, 2022，Professor Chen Xinyu of Tsinghua University Law School published the article "bet365 apuestas's Legal and Political Imprint" on "Rule of Law Weekend"。According to the description of the WeChat public account "Shui Mu Logic" when it was reprinted on August 20，Professor Chen Xinyu was invited to participate in the "Inheritance of the 'Tsinghua School of Logic'" seminar organized by the Joint Research Center for Logic of Tsinghua University on April 21，And spoke at the meeting，"bet365 apuestas's Imprint of Legal Affairs" is an "article based on the speech at the conference"。Professor Chen Xinyu raised a point in the article，It is believed that the time when bet365 apuestas obtained his doctorate should be "1921"，Instead of the usually recorded "1920"。In recent years，The author is in the process of collecting bet365 apuestas’s lost articles and related information，I also saw that there are two different versions of "1920" and "1921" regarding the time when bet365 apuestas obtained his doctorate。Although the author’s point of view is different from Professor Chen，It is still believed that bet365 apuestas received his doctorate in 1920，But the specific situation and process are more complicated，Need to examine carefully。

　　bet365 apuestas’s doctoral thesis was published in 1920

Professor Chen Xinyu proposed in the article，About the time when bet365 apuestas obtained his doctorate，its chronology、Biographies, etc. are all recorded as 1920。Based on the literature the author has seen so far，Indeed it is。For example，Compiled by Liu Cuiyu in 1995、Several versions of bet365 apuestas’s chronology in 2000 and 2004，And Wang Zhongjiang in 1993、1998 and Hu Jun in 1993、bet365 apuestas’s biography or ideological commentary published in different periods such as 2002，The time when bet365 apuestas obtained his doctorate is recorded as 1920。Also，In "Editor's Note" of "The Complete Works of bet365 apuestas" published in 2013，It is also clearly stated that bet365 apuestas received his PhD from Columbia University in 1920。

Professor Chen further proposed，bet365 apuestas Chronology、Biography and other records record the time when he obtained his doctorate as 1920，"The rationale should come from the date attached to the preface of his doctoral thesis (September 1920)"。"But according to the introduction in the book "Sixty Years of Reading History and Reading the World" by He Bingdi, who also graduated from Columbia University，Columbia University requires that the doctoral thesis be published in a book or has a publication guarantee before it can officially award a degree，At the same time, according to the records about bet365 apuestas in "Tsinghua Alumni Records"，Professor Chen concluded: “Strictly speaking，The time when bet365 apuestas obtained his doctorate should be 1921。”Here，bet365 apuestas Chronology、Whether the biography, etc. is based on the time attached to the preface of his doctoral thesis，The author is not sure；What the author can confirm is，bet365 apuestas’s doctoral thesis was “published as a book” in 1920。

In fact，bet365 apuestas’s doctoral thesis was published by W in New York in 1920. D. Gray officially published。The author has checked the original version of this book at the National Library in Beijing，You can also see a card pocket with the words "National Peking Library" printed on the inside of the back cover of the book。Also，The full text of the book can also be downloaded on the HathiTrust Digital Library。According to this information，Combined with Professor Chen’s introduction to the requirements for a doctorate degree from Columbia University by He Bingdi，Can we conclude that bet365 apuestas obtained his doctorate in 1920？I’m afraid not yet。Because except for the time "September 1920" written by bet365 apuestas at the end of the preface of the book，We don’t know exactly when the book was published in 1920，Probably September 1, 1920，It may also be December 31, 1920；And，We need to at least think about it after the book is published，Specific procedures for formal submission to Columbia University、Requirements and required time, etc.。This way，Our attention naturally shifts to another basis for Professor Chen to draw his conclusion，That is, "Records about bet365 apuestas in "Tsinghua Alumni Records"。

　　The data source of "bet365 apuestas of Academicians" is more reliable

Professor Chen did not specify which version of "Tsinghua Alumni Records" he based on，The author checked the 1933 and 1937 versions that are commonly cited in academic circles，The time when bet365 apuestas obtained his doctorate is indeed recorded as 1921。Both versions of "Tsinghua Alumni Records" are edited by Tsinghua University，The then principal Mei Yiqi personally wrote the preface。However，The author is mainly concerned about their data sources。According to the "Editor's Note" of the 1933 edition，"Compilation and printing of this classmate list""Survey form issued by the school"，But "half of it has not been returned yet，The current address and current occupation of most students cannot be published”；Also，“Because many of my classmates are looking forward to the early publication of the classmate records，Therefore we cannot wait for a leisurely investigation”，Also includes "the degrees obtained by some students studying in the United States in the subjects studied at the schools in the United States and the year and month when the degrees were awarded, etc.，Not fully specified”；There is also "the questionnaire issued this time，The minimum number of students who are special students and former graduates who use subsidies must be sent back，There are no detailed records for reference regarding these three types of students，So the investigation is more difficult”。Of course，Editor’s Commitment，“Everything that is missing or wrong，All corrections shall be made when reprinting”。

The 1937 edition of "Editor's Notes" specifically introduces the "investigation method for this record": "The school has issued questionnaires many times，There are very few people who have recovered it。In addition, those who can be found by visiting at any time，Alumni letters and conversations are good materials，Return of "Alumni Newsletter"，This is also an opportunity for us to inquire via separate letters。”Also，The editor also specifically mentioned: “This new questionnaire was filled in by those who did not respond because it was too late to make changes，And beg for forgiveness。”As for the recorded names of each student、alias、Birth year、Information such as place of origin and education，"The ones he told each time are different from the most recent one"。If you look at it this way，The records about bet365 apuestas in the 1933 and 1937 versions of "Tsinghua Classmates" are relatively complete，The reliability of its content should be relatively high。In other words，No matter which version Professor Chen is based on the records in "Tsinghua Alumni Records"，His conclusion that bet365 apuestas obtained his doctorate in 1921 has some validity。It’s just that the author happened to have seen another similar record about bet365 apuestas，Compiled and printed in June 1948、bet365 apuestas's resume in the "Records of Academicians of the National Academia Sinica" (First Series) (hereinafter referred to as the "Records of Academicians") signed by Zhu Jiahua，The time when he obtained his doctorate is recorded as 1920。

Comparing "Records of Academicians" with "Records of Tsinghua Alumni"，Which record about the time when bet365 apuestas obtained his doctorate is more reliable？The key is to look at the source of information in "Records of Academicians"。March 1948，bet365 apuestas was elected as the first academician of Academia Sinica，"Academician Records" is a basic introduction to the first 81 academicians，Includes two parts: resume and bibliography。Follow the instructions in the book's "Routine Examples"，The resumes of academicians mainly include seven items: 1.Current position；2.Date and place of birth；3.Family - Immediate Relatives；4.Education；5.Experienced positions；6.Participate in academic groups；7.Now Communications Office。Questions about the source of resume content，The "Fanli" also specifically states: "The records in this series are based on the principle of the person filling in the information，Record if necessary，If there is nothing, open it。"Except for the third item of bet365 apuestas's resume, "Family - Immediate Relatives", which is "Kai Zhi"，Every other item is "recorded"，The "academic qualification" is written like this: Tsinghua School (1911-14)；Bachelor of Business School, University of Pennsylvania, USA (1917)；Master of Graduate Studies, Columbia University, USA (1918)，Doctor (1920)。

If based on the source of the information，As well as the principle of "if the previous reports differ, the most recent ones" in the 1937 edition of "Records of Tsinghua Alumni"，The record in the "Records of Academicians" that bet365 apuestas received his doctorate in 1920 may be more reliable。The author once combined the fact that bet365 apuestas’s doctoral thesis was published in 1920，Also prefer the records in "Records of Academicians"，But there is always a confusion in my heart: it stands to reason，The time to obtain a doctorate should be relatively clear and definite，Why do the records about bet365 apuestas exist at two different times: "1920" and "1921"？These two times have their direct basis，At one time, the record was incorrect due to editing errors or various accidental factors such as typographical errors？And if there are records about bet365 apuestas in "Records of Tsinghua Alumni" and "Records of Academicians"，These are indeed true reflections of the contents of the "questionnaire" and "fill-in" that he "filled back"，Then this confusion will be even stronger，Unless a more direct one can be found、Original first-hand information。

　　Student list in "Columbia bet365 apuestas at a Glance"

April 19, 2022，Columbia University Archives responded to a consultation email from the author，There are exactly two pieces of information directly related to the time when bet365 apuestas obtained his doctorate，A handbook for Columbia University’s 167th Commencement on June 1, 1921，The other is bet365 apuestas’s alumni information card。In the Commencement Handbook，bet365 apuestas’s name (English name Yueh Lin Chin) appears in the list of recipients of Doctor of Philosophy degrees。This seems to be a direct basis for bet365 apuestas to obtain his doctorate in 1921，It can even be accurate to the specific day。But it’s on bet365 apuestas’s alumni information card (the specific content is handwritten)，The column filled in with the date of obtaining a doctorate is “1920”；And look carefully，You will find that the "0" in the number "1920" seems to be modified from "1"，In other words，The original filled in may be "1921"。If "1921" is really changed to "1920"，Who modified it?？Why modify it？Even if it has not been modified，How to explain the discrepancy between the two records provided by the Columbia University Archives？These questions have forced me to return to Columbia University’s basic regulations on granting doctorate degrees，Collect further information related to this。

Columbia University has a series of basic regulations and requirements for the award of doctorate degrees，Based on "Columbia University at a Glance" (1920-1921) (Catalogue, 1920-1921)，PhD diploma is awarded at three times each academic year，October respectively、February and June，Ph.D. candidates must apply for the final oral examination for the doctoral degree at least two months in advance。Also，Before the award of the Ph.D.，PhD candidates should print and publish their doctoral thesis，And submit 100 copies to the University Librarian。The Institute of Political Science where bet365 apuestas works also specifically requested，The doctoral thesis must be printed and published before the final oral examination。These basic regulations and requirements are the same as described in the Columbia University List for the 1918-1919 and 1919-1920 academic years。Of course，The above are only some of the basic regulations and requirements，There are also different majors in other Columbia University information bulletins，Including specific regulations and special requirements between different departments of the Institute of Political Science。When exactly was bet365 apuestas awarded his doctorate in 1920 or 1921?？

The author in "Columbia University at a Glance" (1921-1922) (Catalogue, 1921-1922) Find a list of students who were awarded degrees in the academic year 1920-1921。Degrees were awarded at the University Council meetings in October 1920 and February 1921, and on Commencement Day in June 1921，Except graduation day，Students who were awarded degrees at the other two times will be noted with a special label，If there are special circumstances, they will be explained after the name。Among them，bet365 apuestas’s name is marked with “*”，Indicates that he was awarded a doctorate in philosophy in October 1920。According to the Columbia University academic calendar，The October 1920 University Council meeting was held on October 19th。At this time，The author recalls an important detail，In the graduation ceremony manual mentioned above，There is no specific distinction and labeling of the different times when students are awarded degrees。In other words，Student list in graduation ceremony handbook，Some are indeed awarded degrees on graduation day，The other part was actually awarded the degree at another time，bet365 apuestas happens to belong to the latter。

The above is based on the author's article "bet365 apuestas's Imprint of Legal Affairs" by Professor Chen Xinyu，Combined with the relevant information collected so far，An examination of the issue of when bet365 apuestas obtained his doctorate。Based on the above analysis，The author’s point of view is different from that of Professor Chen，Still believe that bet365 apuestas received his doctorate in 1920，Specifically October 19, 1920；If there is other information, it is recorded as 1921，Then its initial basis may be the record about bet365 apuestas at Columbia University’s 167th graduation ceremony on June 1, 1921。

However，The author is clearly aware of the shortcomings and limitations of his own views，There are still many important details that need further verification，At least in terms of information，The original minutes of the Columbia University Board of Trustees meeting on October 19, 1920 have not yet been collected、bet365 apuestas’s doctoral degree certificate and other key first-hand information；In terms of specific analysis，The author is mainly based on normal thinking and assumptions，without fully considering the special circumstances that may occur，The reason is still the lack of first-hand information。Also，Examine the "truth in history" such as "the time when bet365 apuestas received his doctorate"，It may not have any substantial impact on the ideological research of "pure philosopher" bet365 apuestas。Just，Since known sources have different records on this issue，Academia also has different views on this issue，That needs to be taken seriously。
