August 18, 2022，Professor Chen Xinyu of Tsinghua University Law School published an article "Jin Yuelin's Legal Seal" in "The Law Weekend"。According to the explanation of the WeChat public account "Mizuki Logic" on August 20th，Professor Chen Xinyu was invited to participate in a special seminar on the "Tsinghua Logic School" special seminar organized by the Tsinghua University Logic Research Center on April 21，Speaking at the meeting，"Jin Yuelin's Legal Seal" is "article based on the conference"。Professor Chen Xinyu put forward a point of view in the article，The time for Jin Yuelin to obtain a doctorate degree should be "1921"，instead of "1920"。In recent years，I am in the process of collecting Jin Yuelin's 佚 佚，I also saw that the time for Jin Yuelin to obtain a doctorate degree has two different sayings: "1920" and "1921"。Although the author’s point of view is different from Professor Chen，I still think that Jin Yuelin obtained a doctorate degree in 1920，But the specific situation is more complicated with the situation，Need to take a closer look。

Professor Chen Xinyu proposed in the article，Time to get a doctorate from Jin Yuelin，Its year table、biography, etc. are all recorded as 1920。According to the literature I have seen currently，Indeed。For example，Liu Peiyu organized 1995、Several versions of Jin Yuelin New Year table in 2000 and 2004，and Wang Zhongjiang in 1993、1998 and Hu Jun in 1993、2002 and other periods published in different periods，Among them, Jin Yuelin's doctoral degree time is recorded as 1920。Another，In the "Complete Works of Jin Yuelin" published in 2013，It is also clearly written that Jin Yuelin obtained a doctorate degree from Columbia University in 1920。

Professor Chen further proposed，Jin Yuelin New Year Table、Biography, etc., record the time to obtain a doctorate degree as 1920，"It should be based on the time attached to the preface of the doctoral dissertation (September 1920)"。"But the introduction of the book" Reading the Sixty Years of History Reading the World ", who also graduated from Ge’ s University,bet365 live casino games ，Colombia University's requirement is that doctoral dissertation is published or existing publication guarantees to officially issue a degree，At the same time, according to the record of Jin Yuelin in the "Tsinghua classmate record"，Professor Chen concluded: "Rigid to say，Jin Yuelin's time for a doctorate degree should be 1921。"" here，Jin Yuelin New Year Table、Biography or not is the time attached to the preface of its doctoral dissertation，The author cannot be sure; what I can determine is，Dr. Jin Yuelin's thesis has been "published into a book" in 1920。

In fact，Dr. Jin Yuelin's thesis was officially published by W. D. Gray in New York in 1920。I have checked the original version of the book at the National Library in Beijing，In the inside of the book of the book, you can also see a card bag printed with the word "National Peiping Library"。Another，You can also download the full text of the book on the Hathitrust Digital Library。According to this information，Based on the introduction of He Bingzheng's relevant requirements for doctoral degree in Columbia University in conjunction with Professor Chen，Is it possible to conclude that Jin Yuelin obtained a doctorate degree in 1920? I'm afraid I can't。Because of the time except the "September 1920" time written by Jin Yuelin in the book,，We don’t know when the book is published in 1920，It may be September 1, 1920，It may also be December 31, 1920; and，We need to consider the book publishing at least，Specific procedures for officially submitted to Columbia University、Requirements and time, etc.。This，Our attention naturally transferred to Professor Chen to get another basis for its conclusion，"Records of Jin Yuelin in" Tsinghua Classmate Records "。

　　The source of the information of "Academician Record" is more reliable 

Professor Chen did not specifically explain which version of the "Tsinghua classmate record" he was based on，I checked the two versions of 1933 and 1937, which are currently referenced by academic circles，Among them, Jin Yuelin's doctoral degree time is indeed recorded as 1921。These two versions of "Tsinghua Classmate Records" are edited by Tsinghua University，The then principal Mei Yiqi personally preface。but but，The author is mainly concerned about their data source issues。According to the 1933 edition of "Editor's Description" introduction，"Compiled bet365 Play online games by the classmate records", "Survey Form issued by the school"，But "Half of the number has not been returned so far，To the present address of most students and the current occupation of the current occupation cannot be published "; in addition,，"Due to the classmates of the classmates, the classmate records the early publishing，Therefore, you can't wait to be calm for a long time "，It also made "some of the disciplines obtained from the discipline and the year of the degree of the discipline of the students who entered the United States at the United States，Failure to completely indicate "; there is also" the survey form issued this time，The minimum person who sent a special student and a former student who returned to the former 肄，And these three types of students have no detailed records for reference，Therefore, the investigation is more difficult "。Of course，Editor's promise，"Everyone who missed this error，All replenish correction when re -publication "。

1937 edition "Editor's Description" specifically introduced the "this record survey method": "The school issued a survey form multiple times，The recovered person is very small。In addition, it is a visit to those who visit at any time，Alumni letters and conversation solid materials，That is, the dejection of "Alumni Newsletter"，It can also be for our opportunity to ask for a letter。""，Editor also mentioned: "The new investigation form is filled back and because the time after late is not too late，and begging for forgiveness。"As for the name recorded by each student、Alias、Life Year、Society and academic qualifications，"Those who have not reported from the past from the recent recent"。If you look at it,，The records of Jin Yuelin in the two versions of the two versions of "Tsinghua classmates" in 1933 and 1937 are relatively complete，Its content reliability should be relatively high。In other words，Professor Chen, no matter which version of the record in the "Tsinghua classmate record"，He reached the conclusion of Jin Yuelin's doctoral degree in 1921。I just met another similar record about Jin Yuelin，that is, in June 1948, edited、Zhu Jiazheng's "Records of Academician of the National Central Research Institute" (first series) (hereinafter referred to as "Academician Record") resume，Among them, he bet365 live casino games obtained a doctoral degree time but recorded as 1920。

That "Academician Record" compared with the Tsinghua classmate record，Which record of Jin Yuelin's doctoral degree time is more reliable? The key is to see the source of the information of "Academician Records"。March 1948，Jin Yuelin was elected as the first academician of the Central Academy of Sciences，"Academician Record" is an introduction to the basic situation of the first 81 academician，Including two parts: resume and book directory。According to the instructions of the "Fan" of the book，The resume parts of the academicians mainly include seven items: 1. The current position; 2. The year and place of birth; 3. Family -Direct relatives; 5. After duties; 6. Participate in academic groups; 7 . Now communication。For the source of resume content，"All Case" also specifically pointed out: "The various records of this series are based on the principle of the person who filled the note，No one to open，No one to open。"Jin Yuelin's resume, except the third item" Family -Family Relative "is" Kai Zhi "，Other items have "recording"，Among them, "academic qualifications" are written like this: Tsinghua School (1911-14); Bachelor of Business School of Pennsylvania University (1917); Master of Columbia University Research Institute (1918)，Dr. (1920)。

If according to the source of the information，and the 1937 version of "Tsinghua Classmate Records" "The principle of" one who has not been reported from the time from the time "，The record of Jin Yuelin in "Academician Records" may be more reliable in 1920。I used to combine the facts that Dr. Jing Yuelin's thesis has been published in 1920，also tend to record the record in "Academician Records"，But I have always had a confusion in my heart: it is reasonable to say，The time to get a doctoral degree should be clear and clear，So why is there two different time of "1920" and "1921"? These two times have their direct basis，Still one of the time or due to various accidental factors such as editing errors or due to typesetting errors? And if "Tsinghua classmate records" and "Academician Records" records about Jin Yuelin，It is indeed the real reflection of the "survey form" and "filling" content of his own "filling back"，This confusion is even stronger，Unless you can find more Bet365 app download direct、Original first -hand information。

　　List of Students in the List of Columbia University 

April 19, 2022，Columbia University Archives in a consultation email of the author，Just two materials are directly related to Jin Yuelin's doctoral degree time，A copy of the 167th graduation ceremony of the 167th Graduation Ceremony of Columbia University，Another part is Jin Yuelin's alumni information card。On the Graduation Ceremony Handbook，The name of Jin Yuelin (English name yueh Lin Chin) appeared in the list of doctoral degrees awarded philosophy。This seems to be a direct basis for Jin Yuelin to obtain a doctorate in 1921，It can even be accurate to which day。But on Jin Yuelin's alumni information card (the specific content is handwritten)，The column of the doctoral degree time is "1920"; and take a closer look，I will find that "0" in the number "1920" seems to be modified from "1"，That is to say，It may be "1921"。If you really modify "1921" to "1920"，Who modified it? Why modify?，So how to explain the differences between the two data provided by the Columbia University Archives? These problems have also inspired the author to return to the basic regulations of the doctoral degree awarded by the University of Columbia，Further collection of information related to this。

Columbia University has a series of basic regulations and requirements for doctoral degree award，According to the "List of Columbia University" (1920-1921) (catalogue, 1920-1921) Introduction，each school year awarded a doctoral degree certificate at three times，October、February and June，and doctoral candidates must apply at least two months in advance to apply for a doctoral degree last oral test。Another，Before awarding a doctoral degree，Doctoral candidates should print and publish their doctoral dissertation，and submit 100 copies to the college book administrator。The Institute of Political Science, where Jin Yuelin is located, also specially requested，Doctoral dissertation must be printed and published before the last oral test。These basic regulations and requirements are the same in the "List of Columbia University" in 1918-1919 and 1919-1920。Of course，The above is just part of the basic regulations and requirements，and there are different majors in other series of information Bet365 app download bulletin at Columbia University，Including specific regulations and special requirements between different departments of the Institute of Political Science。So which time Jin Yuelin was awarded a doctorate degree in 1920 or 1921?

I am at the List of Columbia University (1921-1922) (CataLogue, 1921-1922) Find a list of students who have been awarded in 1920-1921 academic year。The degree was awarded in the university council meeting in October 1920 and February 1921 and the June 1921 Graduation Ceremony.，And in addition to the graduation ceremony day，Students who are awarded by the other two times will be indicated with special tags，If there are special circumstances, it will be explained after the name。Where，Jin Yuelin's name is marked with "*"，It means that he was awarded a doctorate degree in philosophy in October 1920。According to the Columbia University calendar，The university council meeting in October 1920 was held on October 19。At this time，I think of an important detail，That is, the graduation ceremony manual mentioned above，There is no specific distinction and labeling at different times when the students are awarded at different times。That is to say，Student list on the Graduation Ceremony Handbook，Some are indeed awarded a degree on the graduation ceremony day，Another part has actually been awarded a degree at other times，Jin Yuelin just belongs to the latter。

The above is based on the article on Professor Chen Xinyu's "Jin Yuelin's Legal Seal"，Combined with the relevant information collected currently collected，Test the problem of Jin Yuelin's doctoral degree time。According to the above test，The view from the author is different from Professor Chen，I still think that Jin Yuelin's time to obtain a doctorate degree should be 1920，Specifically, October 19, 1920; if there are other information, it is 1921，The original basis for its initial basis may be the record of Kim Yuelin on June 1, 1921, the 167th Graduation Ceremony of Columbia University。

but but，The author clearly realizes the lack and limitations of his own point of view，There are also many important details that need to be further verified，At least in terms of data，It has not been collected at the original record of the Council of Columbia University Council on October 19, 1920、Dr. Jin Yuelin's degree certificate and other key first -hand Bet365 lotto review information; in terms of specific analysis，The author is mainly based on normal thinking and assumption，instead of fully considering the special circumstances that may occur，The reason is still the lack of first -hand information。Another，Examine's "True Truth in History" like "Jin Yuelin Gettoate Division Time"，It may not have any substantial impact on the ideological research of "pure philosopher" Jin Yuelin。Just，Since the known information has different records about this problem，The academic community also has different views on this issue，Then you need to take it seriously。
