Thinking about the death of Sir John Templeton — champion of research into science and religion — reminded me of two passages from Thomas Jefferson. Though Jefferson was sometimes cast as a heretic, I think he and Templeton were kindred spirits.
In this first letter, Jefferson counsels his nephew, Peter Carr, how reason should be his guide, whether it takes him to a belief in God or disbelief.

“Your reason is now mature enough to examine this object. In the first place, divest yourself of all bias in favor of novelty & singularity of opinion. Indulge them in any other subject rather than that of religion. It is too important, and the consequences of error may be too serious. On the other hand, shake off all the fears & servile prejudices, under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear. You will naturally examine first, the religion of your own country. Read the Bible, then as you would read Livy or Tacitus. The facts which are within the ordinary course of nature, you will believe on the authority of the writer, as you do those of the same kind in Livy & Tacitus. The testimony of the writer weighs in their favor, in one scale, and their not being against the laws of nature, does not weigh against them.
But those facts in the Bible which contradict the laws of nature, must be examined with more care, and under a variety of faces. Here you must recur to the pretensions of the writer to inspiration from God. Examine upon what evidence his pretensions are founded, and whether that evidence is so strong, as that its falsehood would be more improbable than a change in the laws of nature, in the case he relates. For example, in the book of Joshua, we are told, the sun stood still several hours. Were we to read that fact in Livy or Tacitus, we should class it with their showers of blood, speaking of statues, beasts, &c. But it is said, that the writer of that book was inspired. Examine, therefore, candidly, what evidence there is of his having been inspired. The pretension is entitled to your inquiry, because millions believe it. On the other hand, you are astronomer enough to know how contrary it is to the law of nature that a body revolving on its axis, as the earth does, should have stopped, should not, by that sudden stoppage, have prostrated animals, trees, buildings, and should after a certain time gave resumed its revolution, & that without a second general prostration. Is this arrest of the earth’s motion, or the evidence which affirms it, most within the law of probabilities?….
Do not be frightened from this inquiry by any fear of its consequences. If it ends in a belief that there is no God, you will find incitements to virtue in the comfort and pleasantness you feel in its exercise, and the love of others which it will procure you. If you find reason to believe there is a God, a consciousness that you are acting under his eye, & that he approves you, will be a vast additional incitement; if that there be a future state, the hope of a happy existence in that increases the appetite to deserve it; if that Jesus was also a God, you will be comforted by a belief of his aid and love. In fine, I repeat, you must lay aside all prejudice on both sides, and neither believe nor reject anything, because any other persons, or description of persons, have rejected or believed it. Your own reason is the only oracle given you by heaven, and you are answerable, not for the rightness, but uprightness of the decision.

From that, we might conclude that Jefferson disbelieved the miracles in the Bible (true) and that he was at least agnostic on the question of whether science proved God’s existence. But later in life we see, in a letter to John Adams, that he believed that science did provide evidence for God’s presence:
“I hold (without appeal to revelation) that when we take a view of the Universe, in its parts general or particular, it is impossible for the human mind not to perceive and feel a conviction of design, consummate skill, and indefinite power in every atom of its composition,” he wrote. This “design,” as he called it, can be seen in many aspects of nature. “The movements of the heavenly bodies, so exactly held in their course by the balance of centrifugal and centripetal forces, the structure of our earth itself, with it’s distribution of lands, waters and atmosphere, animal and vegetable bodies, examined in all their minutest particles, insects mere atoms of life, yet as perfectly organised as man or mammoth, the mineral substances, their generation and uses, it is impossible, I say, for the human mind not to believe that there is, in all this, design, cause and effect, up to an ultimate cause, a fabricator of all things from matter and motion, their preserver and regulator while permitted to exist in their present forms, and their regenerator into new and other forms.” Some Being is the “fabricator” of all these things.

What’s more, he writes, it wasn’t a one time event. Providence is helping to keep this equilibrium. Though he predated Darwin, so we’ll never know what kind of impact evolutionary theory would have had on his theism, Jefferson believed that even the death of living organism and galactic bodies was sign of a “design” from a Creator. “We see, too, evident proofs of the necessity of a superintending power to maintain the Universe in it’s course and order. Stars, well known, have disappeared, new ones have come into view, comets, in their incalculable courses, may run foul of suns and planets and require renovation under other laws; certain races of animals are become extinct; and, were there no restoring power, all existences might extinguish successively, one by one, until all should be reduced to a shapeless chaos. So irresistible are these evidences of an intelligent and powerful Agent that, of the infinite numbers of men who have existed thro’ all time, they have believed, in the proportion of a million at least to Unit, in the hypothesis of an eternal pre-existence of a creator, rather than in that of a self-existent Universe.”
Jefferson and Templeton were both lovers of science, and lovers of God. Rest in Peace, Sir John. I’m hoping you and TJ are hashing this out now.
