Presuppositonalists insist that the senses are not a reliable way to discover truth, and yet they trust them implicitly when it comes to dinnertime: they do not fear that the cheeseburger is actually a rattlesnake poised to strike. Furthermore they have to use their eyes or ears or hands in order to hear or read the Bible, and yet they are perfectly willing to trust their senses for this duty.
Presuppositionalists insist that man’s intellect cannot be trusted because of the effects of the Fall, and yet they must exercise their own intellects when performing exegesis of the Bible. And they are perfectly willing to trust their intellects when doing so.
Presuppositionalists may attempt to escape these dissonances by claiming that the Holy Spirit guides them, but they do not all agree among themselves about the truth. Furthermore this is really special pleading, because those who disagree with them concerning the reliability of the senses and of reason may make the same claim to have been guided by the Spirit.
Aquinas, Etc. 
Hi Fred,
Don’t know if you remember me, it has been awhile since our last chat. This is probably not the place to post the following, but I could not find an email address, so forgive me…
There is a new thread at my blog (
LINK), that may interest you—your expertise in Aquinas would greatly enhance the dialogue, for though I have read a good deal of Aquinas, I am anything but an expert of his thought.
Anyway, sincerely hope that you (or any others who have a good knowledge of Aquinas’s thought) can drop by, and share some insights.
Grace and peace,
David
Hello David!
Thank you for stopping by, and thanks for the heads-up about your post. Unfortunately I do not consider myself to be all that strong on Aquinas’ discussion of the Trinity, so I think it unlikely that I would have anything to contribute. But I will keep an eye on the progress of the conversation, though, and jump in if the opportunity presents itself.
Peace to you,
Fred
