Renaissance Humanism was an intellectual movement typified by a revived interest in the classical world and studies which focused not on religion but on what it is to be human.

Humanists believed in the importance of an education in classical literature and the promotion of civic virtue, that is, realizing a person's full potential both for their own good and for the good of the society in which they live.

Free Will
The only Person who actually has absolute free will is God. All creatures, being slaves (whether of righteousness or unrighteousness – ala Ro 6), are under bondage, including their will, as it is a function of their nature.

Desiderius Erasmus Roterodamus (aka “Erasmus”) – Wikipedia.com
(1466 –1536): a Dutch philosopher and Catholic theologian who is considered one of the greatest scholars of the northern Renaissance. As a Catholic priest, he was an important figure in classical scholarship who wrote in a pure Latin style. Among humanists he enjoyed the sobriquet "Prince of the Humanists", and has been called "the crowning glory of the Christian humanists".

Desiderius Erasmus Roterodamus (aka “Erasmus”) – Wikipedia.com
Using humanist techniques for working on texts, he prepared important new Latin and Greek editions of the New Testament, which raised questions that would be influential in the Protestant Reformation and Catholic Counter-Reformation. He also wrote On Free Will…

“Free Will” WRONGLY Defined by Humanist, Desiderius Erasmus
"Moreover I consider Free-will in this light: that it is a power in the human will, by which, a man may apply himself to those things which lead unto eternal salvation, or turn away from the same."

The Bondage of the Will – Martin Luther
"Free-will" cannot be applied to anyone but to God only. You may, perhaps, rightly assign to man some kind of will, but to assign unto him "Free-will" in divine things, is going too far…But you cannot call him Free, who is a servant acting under the power of the Lord.

The Bondage of the Will – Martin Luther
The Scripture, however, sets forth such a man, who is not only bound, miserable, captive, sick, and dead, but who, by the operation of his lord, Satan, to his other miseries, adds that of blindness: so that he believes he is free, happy, at liberty, powerful, whole, and alive. For Satan well knows that if men knew their own misery he could retain no one of them in his kingdom.

The Bondage of the Will – Martin Luther
THIS, therefore, is also essentially necessary and wholesome for Christians to know: That God foreknows nothing by contingency, but that He foresees, purposes, and does all things according to His immutable, eternal, and infallible will. By this thunderbolt, "Free-will" is thrown prostrate, and utterly dashed to pieces.

What’s the Problem?
Man is forever trying to usurp God’s power and authority, more succinctly, His sovereignty! This is tantamount to saying the human flesh wishes for independence from God.
