In the early Freiburg period (1919-1923)，The core issue in Heidegger’s thought is “actual life experience”。This period，The question of "bet365 sign up offer" has not yet acquired the status that the later Heidegger gave it。But，Through “real life experience”，Especially the explanation of its "pre-theoretical" and "turbulent" characteristics，Heidegger in the early Freiburg period had acquired a different view of bet365 sign up offer than the traditional one，And as the "origin" in Heidegger's sense, it fundamentally affected his later view of bet365 sign up offer。

Looking back at the initial development of Heidegger’s thought，We can clearly see that "actual life experience" is closely related to the question of bet365 sign up offer from the beginning，It flows from Heidegger’s original motivation of pursuing “the bet365 sign up offer of life”。After breaking into the field of life experience during the wartime urgent semester lectures in 1919，He is not only opposed to seeing bet365 sign up offer as validity，Also opposed to understanding bet365 sign up offer as something valuable，But that actual life itself is in the bet365 sign up offer，It is a true existence in itself，It’s the bet365 sign up offer，Thus ultimately traces back to the bet365 sign up offer of actual life experience itself。The lecture "Augustine and Neoplatonism" in the summer semester of 1921 shows: this "bet365 sign up offer of life，Not theoretical”，rather pre-theoretical，It is the bet365 sign up offer in the most original sense。

In urgent need of semester lectures in wartime，Heidegger uses the Greek word “a-letheia” for the first time，That is, "to remove - cover"，To mean "bet365 sign up offer"。This means，There is an inherent relationship between bet365 sign up offer and untruth、Fundamental connection。In Lecture "Introduction to the Phenomenology of Religion" during the winter semester 1920/21，He had the following insights: On the one hand，The authentic self carries within itself the illusion，Due to various temptations，The true self covers itself again and again in real life；But on the other hand，In the tendency to surrender oneself to self-sufficient practical life，There is also a tendency towards bet365 sign up offer，Because facing the possibilities opened by fear，The implications of the surrounding world can no longer be considered，The true self can be revealed and experienced，Heidegger calls this “existential bet365 sign up offer”。

The lecture "The Phenomenological Interpretation of Aristotle: An Introduction to Phenomenological Research" in the winter semester of 1921/22 further showed that "actual life experience" or "Dasein" itself has always been in a state of "decline-reflection" amidst the turmoil of decline。In other words，It has always been in the dual operation of bet365 sign up offer and unreality。And this is precisely the most original bet365 sign up offer of life，Or the bet365 sign up offer of life。Accordingly，Heidegger clearly pointed out in the Natop Manuscript: sinking is a constitutive factor of the reality of life，It is not an occasional evil feature of life，But it cannot be completely eliminated。

　The lecture "Ontology—The Hermeneutics of Practicality" given in the summer semester of 1923 was the last lecture given by Heidegger in his early Freiburg period，It is also a summary and deepening of his thoughts during this period。In this lecture，Heidegger realized，“Logos” is a special way in which actual life reveals itself and reveals beings。In its original sense，“Logos” does not refer to reason，It refers to speech、Speech。Logos as speech has a special possibility of “making it true”。In other words，It can uncover what was previously covered。Also，Heidegger also discovered，Only the prior unfolding state from the meaning，And in this expanded state，Only in Dasein can we encounter beings。This expanded state has two unified characteristics，That is, prior availability and prior appearance of the public world。Dasein and meaning are originally in a state of familiarity，So it is aware of this expansion state，In other words, there is a prior understanding of it。In this sense of “having prior understanding”，Heidegger calls "Dasein" "bet365 sign up offer"。That which manifests itself in the bet365 sign up offer of Dasein，In bet365 sign up offer in the sense of "uncovered state"。

What is particularly important is，bet365 sign up offer lecture "Ontology—The Hermeneutics of Practicality"，Heidegger has clearly seen that self-shielding belongs to the "existential characteristics" of existence。here，He elaborated on "self-shielding" from two levels: on the one hand，It means that actual life always reveals itself in some way，But in relief，That is, always driving certain aspects of oneself into darkness；On the other hand，It refers to actual life experience, although it always has a prior understanding of one's own existence and existence itself，But this kind of prior understanding is usually not one’s own，That is, the true self usually disappears bet365 sign up offer surrounding world and does not appear，Authentic self-understanding needs to be fought for through the anti-decline movement。

Heidegger’s understanding of “bet365 sign up offer” in his early Freiburg period，The concept of "bet365 sign up offer" that fundamentally guided him during his Marburg period。

The preface of the first lecture of Heidegger's Marburg period (1923-1928) (the lecture "Introduction to Phenomenological Research" in the winter semester of 1923/24) raised the basic questions of phenomenological research，Although it does not involve the issue of "bet365 sign up offer"，But including "language" issues。In the first part of this lecture，Heidegger discusses Aristotle’s concepts of “phenomenon” and “logos”。He pointed out: For the phenomenon of "light"，“Darkness” is completely positive。Language as a mode of existence of Dasein can bring phenomena into the light，But since language always speaks of something as something，Thus there is the possibility of seeing the person being addressed as an other rather than as himself，Thus cheating、Illusion、The possibility of occlusion exists simultaneously from the beginning，As long as Dasein exists as speech，Then it itself is the source of "falseness"。It can be said，There is a lie in the reality of language，It is precisely language that obscures things。This way，The manifester in the original sense of "self revealing itself" will become an illusion。And，The more concrete Dasein is in the world，False lies more than oneself。This is obviously a further deepening and concretization of Heidegger’s concept of bet365 sign up offer in his early Freiburg period。

And，In this lecture given in the winter semester 1923/24，Heidegger discusses Descartes’ view of bet365 sign up offer，The first thematic discussion of the issue of bet365 sign up offer - what is the bet365 sign up offer of life and existence？He pointed out，bet365 sign up offer is not a characteristic of theoretical cognition，But the basic state of life itself。But，As pointed out in the 1924 summer semester lecture "Basic Questions of Aristotle's Philosophy"，Dasein first、Normally、Not initially in its own "this"，But live among ordinary people。It does not see or deliberately avoids its own disclosure，For what is revealed in its unveiling is the bet365 sign up offer of life，That is, its homeless status。So，The authentic state of existence requires a certain way of caring，Snatched from other possibilities，And this kind of "robbing" is also possible。Heidegger pointed out in his 1924 lecture entitled "The Concept of Time": The authenticity of Dasein is the most extreme possibility of its existence，Death is such a possibility，Thus by going first into death，Dasein can be in the fear of "nothing"，Determine true survival。Because，In this fear，Being in the world is transformed into pure absence。So，The lecture "Plato's "The Sophists"" in the winter semester of 1924/25 clearly stated: bet365 sign up offer is a deprived concept。The lecture "Logic: The Question of bet365 sign up offer" in the winter semester of 1925/26 also said: Authenticity and non-authenticity are the basic possibilities for the existence of Dasein，The question of bet365 sign up offer and the question of existence are intertwined。Such a concept of bet365 sign up offer obviously also originates from Heidegger’s understanding of the turmoil of “actual life experience” during his early Freiburg period。

It can be seen from the above，Heidegger is obviously not as Tugenthalt said，The concept of bet365 sign up offer is first developed in Section 44 of "Being and Time"。Understanding of bet365 sign up offer in different meanings and levels during Heidegger’s Marburg period，There are already corresponding germs in his early Freiburg thoughts，The former is ultimately derived from the obviousness of "actual life experience"、Relief、Historic、Pre-theoretical characteristics such as practicality and the turbulent characteristics of "preconstruction-retrospection" and "decline-anti-decline"。To properly understand Heidegger’s view of bet365 sign up offer during the Marburg period，We need to return to the view of bet365 sign up offer he obtained through the interpretation of "actual life experience" during his early Freiburg period。Not only that，Anyone familiar with Heidegger’s later thought can clearly see that the core elements of Heidegger’s concept of bet365 sign up offer after the Marburg period can also find their “origins” in his early Freiburg period view of bet365 sign up offer。
