What does virtual mean in Bergson s theory

Bergson divides time into two types.

One is the time of life.

One is the time of death, which refers to the time of what we usually call the time of the hour, that is, the time in the epistemological sense.

Living time refers to the extension of time, time in the ontological sense.

This is a philosophical question, and it may not be easy to find the answer on the part of the psychiatric department. There is an article in the library "On the Effect of Bergson's Mental Time on Stream of Consciousness", which has a brief introduction. For more details, you may have to find a philosophy book.

The essence of life, the meaning of life, stretches like this flowing water, and it rushes endlessly. Intuition is neither a feeling, nor an inspiration, nor a vague induction, but a masterfully designed approach, even the most elaborate philosophical approach, in which intuition is understood in terms of method already means continuity. "These reflections on continuity seem to us to be decisive".

It involves a transition, a generation, a change, yet a continuous generation, a change in reality itself.

Bergson argues: "Wherever something exists, there is a recorder that is recording time, exposed somewhere". But the time in question here is not mathematical time, i.e., it is not a homogeneous collection of moments that are external to each other.

According to Bergson, mathematical time is really a form of space; The time that is extremely important for life is what he calls prolongation. Continuity makes the past and the present into an organic whole, in which there is interpenetration and undifferentiated succession. "Within our ego there is a succession without mutual externality; Outside of the self, that is, in pure space, there is a mutual externality without succession".

Henri Bergson (1859-1941) was a French philosopher. Born in Paris on October 18, 1859. His father is a Pole of Jewish origin, and his mother is an Irish Jew.

Bergson received a typical French education from an early age, with a deep interest in philosophy, mathematics, psychology, biology, and a special love of literature. In 1878 he entered the École Normale Supérieure in Paris, where he received a bachelor's degree in philosophy in 1881 and a doctorate in philosophy in 1889. In 1897 he was a lecturer at the École Normale Supérieure, in 1900 he was a professor at the Collège Française, in 1901 he was elected a fellow of the Academy of Ethics and Political Sciences, in 1914 he was elected president of the Academy of Sciences and was elected a member of the French Academy of Sciences.

During World War I, he entered politics as a scholar, serving as ambassador to Spain and the United States. In 1919 he was a member of the French Supreme Council for Culture and Education, and in 1922 he was the first chairman of the Committee on Cultural Cooperation of the League of Nations.

The philosophy of life advocated by Bergson is a reversal of the cultural trend of modern scientism. He advocated intuition and devalued reason, believing that science and reason can only grasp the relative motion and the surface of reality, but cannot grasp the absolute motion and reality itself, and only through intuition can we experience and grasp the "continuity" of the existence of life, the only true ontological existence. "It places people in reality, and it doesn't look at reality from an external point of view, it relies on intuition, not analysis.

The "Introduction to Metaphysics" is a method of recognizing and comprehending reality, which is called intuitionism in the history of philosophy. In The Evolution of Creation, he also proposes and argues for the impulse to life. The "life impulse" is not only a subjective and irrational psychological experience, but also the cosmic will to create all things.

The instinctive upward eruption of the "life impulse" produces spiritual things, such as man's free will, soul, etc.; The downward fall of the "life impulse" produces inorganic, inert physical things. Bergson's philosophy of life has a strong idealism and mysticism, but its criticism and impact on various forms of rationalist cognition is indeed of great significance to the emancipation of the human spirit, so it has not only become an important philosophical foundation of modernist literature and art, but also has a great influence on modern science and philosophy. The philosopher James Whitehead, the writer Proust, the painter Monet, and the writer Debussy all praised Bergson's doctrine very much.

Bergson's major works include Time and Free Will (1889), Matter and Memory: A Treatise on the Relationship between Body and Mind (1896), A Study of Laughter (1900), Introduction to Metaphysics (1903), The Evolution of Creation (1907), Life and Consciousness (1911), and The Two Origins of Morality and Religion (1932). His writings are not the usual methodical or abstract methods in philosophy, but have the rigor and simplicity of Condiac in style, and are full of color and metaphor, ornate rhetoric and beautiful style, like the writings of Plato and Bacon.

The question is a bit like "why are potatoes called potatoes, also called potatoes", hehe

Henry Bergson, in his 1897 book The Evolution of Creation, declared that all the most enduring and productive philosophical systems are those that are derived from intuition.

The additional: virtual keyword is used to decorate methods, spoofing properties, indexers, or event declarations, and allows these hail objects to be overridden in derived classes. For example, this method can be overridden by any class source bend that inherits it.

This indicates that this function is a virtual function, and when called, it dynamically bonds a method that determines whether the base class or the derived class is called.

virtual polymorphism refers to passive polymorphism.

Kinetic polymorphism is achieved through inheritance, virtual functions, and pointers.

class a

class b : public a

Use: a a* = b();

a->func();

Output: b::func().

No functions are called during compilation, and the compiler only checks for syntax issues when compiling to a->func(). The compiler doesn't know whether it's calling A or B func(), and since A is a pointer to a B object, A only knows that it's pointing to an A (or A) object. Usually the ensemble system illustrates (due to the public inheritance) that b is a kind of a.

During runtime, A wants to call the func() function of the object that A points to, so it gives the command to call func() to the object it points to, and the result A points to a B object, and this object calls its own version of the func() function (version B), so the output is b::func().

Difference from overload:

1) Several functions of the overload must be in the same class;

The overridden function must be in a different class that has an inheritance relationship.

2) The functions to be covered must have the same function name, parameters, and return values;

The overloaded functions must have the same function name and different parameters. The purpose of different parameters is so that the compiler can use the arguments to determine which function the program is calling. This naturally explains why functions can't be overloaded with different return values, because it's very likely that the program won't care about the return value when it calls the function, and the compiler won't be able to tell which function the program is calling from **.

3) The overridden function must be preceded by the keyword virtual;

Overload and virtual have nothing to do with each other, and adding or not adding does not affect the operation of overload.

Resources.

Yes, for virtual functions, the C++ compiler reserves a function pointer-sized space for each of these functions at a fixed location in the class.

These function pointers are populated as the object is constructed.

Because these pointers are fixed in both the parent and child classes, "I'm calling the first function" and "I'm calling the second function" when calling

Just translated. I'm going to call the function pointer on the first position" "I'm going to call the function pointer on the second position".

These pointers point to different ** for different objects.

Therefore, even if the same type of pointer is called, the same function can be executed, and the principle is that in the object that the pointer points to, these "function pointers" point to different points.
