While the evidence may not be scientifically thorough, there’s certainly enough to suggest that porn has a negative impact on our lives.

The very thing in the brain that is the mark of adulthood and maturity is the thing that is eroded as we view more porn. It is as if the brain is reverting, becoming more childlike. “Adult” entertainment is actually making us more juvenile.

The Catholic Church’s teaching on the evil of pornography is anchored in the dignity of the human person and in the intimately conjoined virtue of chastity. Chastity is not (as current stereotypes insist) prudishness, the fearful contempt of sexuality as a “necessary evil,” unavoidable but ultimately subhuman. It is the virtue that both expresses and preserves the dignity of what is a genuine and surpassing good: the dignity of the human person in sexual matters.
