The concept of "a priori" in Kant
The eighteenth-century German philosopher [Immanuel Canto. Immanuel Canto./villagepump/Kant.icon argued that philosophy, like mathematics and the natural sciences, must acquire an inevitable and universal way of thinking. And to do so, independent of all human experience, Reason itself must be able to determine the framework of perception. This is "a priori recognition" (a priori recognition, which is not mixed with any experiential matter at all, is called "unaided perception"[2].
What kind of perception is totally independent of experience?

According to Kant, Hours. and space are a priori concepts. Because these two are concepts that are recognized prior to any empirical recognition [Note 1].
It is not absolutely self-evident that these two precede each other, but what Kant is emphasizing is that nothing can be recognized as pure intuition unless these two are given, as long as "Ding an sich" cannot be recognized.
Note that these two are not naturally imagined times or spaces, but formal ones. They are given to pure intuition because of a new configuration', as Kant himself supports the metaphor that even though the senses feel' that the sun revolves around the earth, it does not in fact do so [Note 2].
In this case, by discarding experience and senses, we can obtain a comprehensive judgment that the earth orbits the sun.
This space is prior to physical space (i.e., a priori). Note also the concern that if pure intuition is not possible, we fall into Humean scepticism.
