In Luke 15:11-32, this signifies people who waste heavenly riches, namely the knowledges of good and truth. (Arcana Coelestia 9291[6], Apocalypse Explained 279[6])

'Look not back behind thee,' as in Genesis 19:17, means that Lot, who represents the good of charity, should not look to matters of doctrine. 'To look up,' is to look to celestial things. In Genesis 18:22, looking signifies thinking because seeing denotes understanding.
