All acts of consciousness require volition. The perception process has volition inseparably bound up within it. The point is to exercise wise attention.
" “Monks, there are these two conditions for the arising of wrong view. Which two? The voice of another and inappropriate attention. These are the two conditions for the arising of wrong view.”
“Monks, there are these two conditions for the arising of right view. Which two? The voice of another and appropriate attention. These are the two conditions for the arising of right view.”
—Anguttara Nikaya 2, 125-6
“The voice of another” includes reading which builds the dhamma knowledge facilitating acts of appropriate attention to be made, and consequently the progressive development of right view (Majjhima Nikaya 117). Appropriate attention develops right view through recognition of the benefits that flow from it.
"The Blessed One said, “Monks, before my self-awakening, when I was still just an unawakened Bodhisatta, the thought occurred to me: ‘Why don’t I keep dividing my thinking into two sorts?’ So I made thinking imbued with sensuality, thinking imbued with ill will, & thinking imbued with harmfulness one sort, and thinking imbued with renunciation, thinking imbued with non-ill will, & thinking imbued with harmlessness another sort.”
An act of appropriate attention and right effort:
"“As I noticed that it leads to my own affliction, it subsided. As I noticed that it leads to the affliction of others… to the affliction of both… it obstructs discernment, promotes vexation, & does not lead to Unbinding, it subsided. Whenever thinking imbued with sensuality had arisen, I simply abandoned it, dispelled it, wiped it out of existence.”
"“And as I remained thus heedful, ardent, & resolute, thinking imbued with renunciation arose in me. I discerned that 'Thinking imbued with renunciation has arisen in me; and that leads neither to my own affliction, nor to the affliction of others, nor to the affliction of both. It fosters discernment, promotes lack of vexation, & leads to Unbinding.”
Majjhima Nikaya 19
