Deleuze's philosophy can be regarded as a response to the 'insufficiency of the faculties of perception', a means to address 'reality' or things which 'do not explicitly strike our sense or consciousness'.

Deleuze uses the concept of 'intensity' to describe elements at the limits of perception.They cannot be e directly perceived. Rather they can only be felt, sensed or perceived in the ‘quality’ they give rise to.--- eg the 'intensity' of a single colour.

Intensity for Deleuze and Guattari refers to movement being permanent to matter itself rather then being a force that moves the objects from the outside. They held that art by necessity exposes the viewer/listener to an impersonal, differential flow of life that is felt rather than understood or comprehended.

In Deleuze's view, art ruptures extensive or everyday perception because it draws attention to singular 'intensities' (such as the vibrancy of a colour). Art draws attention to this virtual flux. It transforms recognisable feelings (affections) and perceptions into impersonal affects and percepts: forces of sensation that are unrecognisable or a-signifying.

Deleuze suggests that the aim of art is to invent new affects and, therefore, to create new possibilities for perception and experience
