Anschauung

It, however, connotes a more nuanced definition especially when the concept is applied to philosophical discourse, including quantum theory.

Anschauen or Anschauung, as a philosophical concept (intuition), has been identified in Plato's Allegory of the Cave where it was associated with the terms light, sun, and eye.

[6] In this definition, he distinguished Anschauung from Vorstellung, which pertains to the philosophical concepts (metaphorical or analogical senses) and their dependence on sensory contents.

[7] Arthur Schopenhauer's definition described the term as what transpires once the eye senses an external object, recognizing it as the cause of the vision.

[9] In this definition, there is a rejection of Schopenhauer's version of the concept, as it denies the abstract idealism of the will as well as "its objectifications of the world of representations".

[12] These constitute the sense-impressions identified as facts and are inherent in nature, existing prior to ideas, which are constructs of such impressions.

[13] In Fichte's doctrine of knowledge, Anschauung plays a role in the perception of the external objects and is united with the notion of Denken.

[17] For Schopenhauer, Anschauung is not the common conception of idea since it should be understood as intuition and requires a higher degree of intellect.
