In Buddhism the faculty of faith (conviction) is expected to be balanced with the faculty of wisdom (discernment), and the practitioner is asked to investigate and test the object of their faith, that is the function of the factor of awakening of investigation.
“Contemplating, he makes an exertion. Exerting himself, he both realizes the ultimate meaning of the truth with his body and sees by penetrating it with discernment.”—-MN 95
“And as for me, I have known, seen, penetrated, realized, & attained it by means of discernment. I have no doubt or uncertainty that the faculty of conviction… persistence… mindfulness… concentration… discernment, when developed & pursued, gains a footing in the Deathless, has the Deathless as its goal & consummation.”—-SN 48.44
“Nevertheless, direct experience constitutes the central epistemological tool in early Buddhism. According to a passage in the Saíãyatana Samyutta, it is in particular the practice of satipatthãna that can lead to an undistorted direct experience of things as they truly are, independent of oral tradition and reasoning.”—-Analayo
“In this, monks, a monk seeing an object with the eye recognizes within himself the presence of lust, hatred or delusion, knowing ‘Lust, hatred or delusion is present in me,’ or he recognizes the absence of these things, knowing ‘There is no lust, hatred or delusion present in me.’ Now, monks, as regards that recognition of the presence or absence of these things within him, are these matters to be perceived by faith, by persuasion, by inclination, by rational speculation, by delight in views and theories?”
“No, indeed, Lord.”
“Are not these matters to be perceived by the eye of wisdom?”
"Indeed, Lord.”—-SN 35.152
