To talk of comprehension as a cause of freely-willed effects is nonsensical. The rest begs the question. The issue is whether any of us at any time is responsible for his or her actions. A person is free insofar as they are not constrained by internal or external factors. Nobody is absolutely free and the degree of freedom anybody has seems determined in large part, if not completely, by factors beyond one's control, such as genetic, environmental, social and historical factors.
Some constraints hinder one's ability to comprehend things.
Others hinder one's ability to control one's thoughts or actions. I may be wrong, but I think this is clear enough for most of my readers. Jan 2001 Thank you for creating and maintaining this wonderful resource. The Skeptic's Dictionary is a lifeboat of reason in the vast deluge of nonsense. Among the items I particularly value are the links for young skeptics, and I have introduced my enthusiastic nine-year old daughter to them.
