Studiousness is the good habit of a man who uses his God-given intellect and reason for the purpose of accumulating knowledge in service of God and the good of others. The Studious man pursues knowledge which is useful and not corrupting, in moderation and in proportion to his vocation and abilities. 

Opposing Studiousness, a man embraces the opposing vice of Curiosity by which a man seeks information, images or sounds from corrupt sources which oppose God through the promotion of immoral or demonic material and/or excessively seeks intellectual stimulation in the pursuit of the lewd, morbid, trivial or frivolous; today, the vice of Curiosityis rampant because evil and addicting media is instantly available.
