Rationally

Concerning the lenity of God, upon which you have most rationally dilated, the 10th chapt. of the 1 booke of Proclus would extreamely delight you.

[…] inasmuch as nothing was really and rationally to be hoped for but a long continuance of the siege and wearying out of the English, they were naturally a little afraid of Joan's impetuous notions. He said— “You see, we are sure that the waiting game is the best, whereas you would carry everything by storm.”

Although computers are a twentieth-century invention, computationism is much older, descending from Newton's contemporary Leibniz (and, arguably, more remotely from the Pythagoreans). It holds that everything is rationally intelligible only so far as it instantiates mathematical rules and ratios. As understood by Leibniz and his followers, computationism was explicitly hostile to all versions of materialism.

The conflict is rationally resolvable either by correcting the mistaken belief or by bringing the wayward desire under rational control.
