Circular Reasoning?

intro2“The charge is made that we engage in circular reasoning. Now if it be called circular reasoning when we hold it necessary to presuppose the existence of God, we are not ashamed of it because we are firmly convinced that all forms of reasoning that leave God out of account will end in ruin. Yet we hold that our reasoning cannot fairly be called circular reasoning, because we are not reasoning about and seeking to explain facts by assuming the existence and meaning of certain other facts on the same level of being with the facts we are investigating, and then explaining these facts in turn by the facts with which we began. We are presupposing God, not merely another fact of the universe. If God is to come into contact with us at all it is natural that the initiative must be with him. And this will also apply to the very question about the relation of God to us. Accordingly, it is only on God’s own testimony that we can know anything about him.”

Spiral Reasoning

screen-shot-2016-11-11-at-11-46-22-am“For this reason we have spoken of the Christian theistic method as the method of implication into the truth of God. It is reasoning in a spiral fashion rather than in a linear fashion. Accordingly, we have said that we can use the old terms deduction and induction if only we remember that they must be thought of as elements in this one process of implication into the truth of God. If we begin the course of spiral reasoning at any point in the finite universe, as we must because that is the proximate starting point of all reasoning, we can call the method of implication into the truth of God a transcendental method. That is, we must seek to determine what presuppositions are necessary to any object of knowledge in order that it may be intelligible to us. It is not as though we already know some facts and laws to begin with, irrespective of the existence of God, in order then to reason from such a beginning to further conclusions. It is certainly true that if God has any significance for any object of knowledge at all, the relation of God to that object of knowledge must be taken into consideration from the outset. It is this fact that the transcendental method seeks to recognize.”

The Inescapable Revelation of God

prpbooks-images-covers-md-9780875527895“The sinner’s problem from his point of view is to cast doubt upon this evidence, to make it appear as though the evidence were not clear. With the rich man who lifted up his eyes in torment, it is the effort of every man to put the blame for his failure to serve God upon the elusive character of the evidence for God’s existence. If he could rightly say that God has to be diligently searched for, that he might possibly be hidden in some remote corner of the earth, or moon or Jupiter, then he would have an excuse for his ignorance. Following Paul, the Reformed theologian, and he alone, will stress the inescapable character of the revelation of God.”

Van Til on Agnosticism

cvtstreet1“With such as these it would seem that the point we should be most anxious to drive home is that in trying to be agnostic, and in trying to say that they have no need of metaphysics, they have already given one of the two possible answers to every question of epistemology that may be asked. They have, as a matter of fact, said that all the facts—or, in epistemological language, they have said that the object and the subject of knowledge—exist apart from God and are able to get along without God. They think they have said nothing at all about ultimate matters, while as a matter of fact they have in effect said everything that could be said about them, and, we believe, more beside. They have tried to be so modest that they did not dare to make a positive statement about anything ultimate, while they have made a universal negative statement about the most ultimate consideration that faces the mind of man. That this charge is fair is apparent from the consideration of the opposite. Suppose that the object and the subject of knowledge do not exist apart from God. Suppose, in other words, that the Christian theistic conception of philosophy is true. In that case, it is not only possible to know something about ultimate things, but in that case the knowledge of proximate things depends upon the knowledge of ultimate things. In that case, not a single fact can be known unless God is known.

What the present-day agnostic should do then is to make his position reasonable by showing that God does not exist. The burden of the proof is upon him. He claims, of course, that the burden of the proof is upon us when we hold that God exists. Yet this is clearly not the case, since his own position, to be reasonable, must presuppose the non-existence of God. If God does exist, man can know him, for the simple reason that in that case all knowledge depends upon him. Hence an agnostic position must first prove that God does not exist.

From these considerations it follows that agnosticism is completely self-contradictory. And it is self-contradictory not only upon the assumption of the truth of theism, but it is self-contradictory upon the assumption of the truth of antitheism, which is the assumption of agnosticism.”

– Cornelius Van Til, A Survey of Christian Epistemology p.212-213

Christian Theism as a Unit

IMG_0567“A truly Protestant method of reasoning involves a stress upon the fact that the meaning of every aspect or part of Christian theism depends upon Christian theism as a unit. When Protestants speak of the resurrection of Christ they speak of the resurrection of him who is the Son of God, the eternal Word through whom the world was made. The truth of theism is involved in this claim that Christians make with respect to the domain of history. And what is true of the resurrection of Christ is true with respect to all the propositions about historical fact that are made in Scripture. No proposition about historical fact is presented for what it really is till it is presented as a part of the system of Christian theism that is contained in Scripture. To say this is involved in the consideration that all facts of the created universe are what they are by virtue of the plan of God with respect to them. Any fact in any realm confronted by man is what it is as revelational through and through of the God and of the Christ of Christian theism.”

– Cornelius Van Til, The Defense of the Faith p.136

The Two Systems

087552480X“The two systems, that of the non-Christian and that of the Christian, differ because of the fact that their basic assumptions or presuppositions differ. On the non-Christian basis man is assumed to be the final reference point in predication. Man will therefore have to seek to make a system for himself that will relate all the facts of his environment to one another in such a way as will enable him to see exhaustively all the relations that obtain between them. In other words, the system that the non-Christian has to seek on his assumption is one in which he himself virtually occupies the place that God occupies in Christian theology. Man must, in short, be virtually omniscient. He must virtually reduce the facts that confront him to logical relations; the “thingness” of each thing must give up its individuality in order that it may be known; to be known, a thing or fact must be wholly known by man…

The system that Christians seek to obtain may, by contrast, be said to be analogical. By this is meant that God is the original and that man is the derivative. God has absolute self-contained system within himself. What comes to pass in history happens in accord with that system or plan by which he orders the universe. But man, as God’s creature, cannot have a replica of that system of God. He cannot have a reproduction of that system. He must, to be sure, think God’s thoughts after him; but this means that he must, in seeking to form his own system, constantly be subject to the authority of God’s system to the extent that this is revealed to him.”

– Cornelius Van Til, A Christian Theory of Knowledge p.15-16

Dependence upon God


“Reformed theology holds to the self-sufficiency of God without compromise. It therefore rejects every form of human autonomy. Only on the assumptions of divine self-sufficiency and man’s complete dependence upon God can the difference between the Christian and the non-Christian points of view be clearly made out. Only thus can the issue be clearly drawn. The non-Christian assumes that man is ultimate, that is, that he is not created. Christianity assumes that man is created. The non-Christian assumes that the facts of man’s environment are not created; the Christian assumes that these facts are created. The Christian has derived his convictions on these matters from Scripture as the infallible Word of God. As self-explanatory, God naturally speaks with absolute authority. It is Christ as God who speaks in the Bible. Therefore the Bible does not appeal to human reason as ultimate in order to justify what it says. It comes to the human being with absolute authority. Its claim is that human reason must itself be taken in the sense in which Scripture takes it, namely, as created by God and as therefore properly subject to the authority of God.”

– Cornelius Van Til, A Christian Theory of Knowledge p.14-15

Knowledge by Authority

We accept this God upon Scriptural authority. In the Bible alone do we hear of such a God. Such a God, to be known at all, cannot be known otherwise than by virtue of His own voluntary revelation. He must therefore be known for what He is, and known to the extent that He is known, by authority alone. We do not first set out without God to find our highest philosophical concept in terms of which we think we can interpret reality and then call this highest concept divine. This was, as Windelband tells us, the process of the Greeks. This has been the process of all non-Christian thought. It is from this process of reasoning that we have been redeemed. On such a process of reasoning only a finite god can be discovered. It has been the nemesis of the history of the theistic proofs that this has been so frequently forgotten. Are we then left with a conflict between Faith and Reason? Have we no philosophical justification for the Christian position? Or are we to find a measure of satisfaction in the fact that others too, non-Christian scientists and philosophers as well as ourselves, have in the end to allow for some mystery in their system?

To all this we must humbly but confidently reply by saying that we have the best of philosophical justification for our position. It is not as though we are in a bad way and that we must seek for some comfort from others who are also in a bad way. We as Christians alone have a position that is philosophically defensible. The frank acceptance of our position on authority, which at first blush, because of our inveterate tendency to think along non-Christian lines, seems to involve the immediate and total rejection of all philosophy—this frank acceptance of authority is, philosophically, our very salvation. Psychologically, acceptance on authority precedes philosophical argument; but when, as epistemologically self-conscious grown-ups, we look into our own position, we discover that unless we may presuppose such a God as we have accepted on authority, the Moment will have no significance. The God that the philosophers of the ages have been looking for, a God in whom unity and diversity are equally ultimate, the “Unknown God,” is known to us by grace. It has been the quest of the ages to find an interpretative concept such as has been given us by grace.

Taking Total Depravity Seriously

prpbooks-images-covers-md-9781596385832It is therefore in Reformed thinking alone that we may expect to find anything like a consistently Christian philosophy of history. Romanism and Arminianism have virtually allowed that God’s counsel need not always and everywhere be taken as our principle of individuation. This is to give license to would-be autonomous man, permitting him to interpret reality apart from God. Reformed thinking, in contrast with this, has taken the doctrine of total depravity seriously. It knows that he who is dead in trespasses and sins lives in the valley of the blind, while yet he insists that he alone dwells in the light. It knows that the natural man receives not the things of God, whether in the field of science or in the field of religion. The Reformed believer knows that he himself has been taken out of a world of misinterpretation and placed in the world of truth by the initiative of God. He has had his own interpretation challenged at every point and is ready now, in obedience to God, to challenge the thinking and acting of sinful man at every place. He marvels that God has borne with him in his God-ignoring and therefore God-insulting endeavors in the field of philosophy and science as well as in the field of religion. He therefore feels compelled to challenge the interpretation the non-Christian gives, not merely of religion but of all other things as well.

Philosophical Apologetics

Following on from The Foundation of Historical Apologetics:

yhst-81483472662466_2189_1292894“In addition to showing that Christ actually arose from the grave and that the facts recorded in the Scripture are as they are recorded as being, insofar as this can be ascertained by historical research, we must show that the philosophy of fact as held to by Christian theism is the only philosophy that can account for the facts. And these two things must be done in conjunction with one another. Historical apologetics becomes genuinely fruitful only if it is conjoined with philosophical apologetics. And the two together will have to begin with Scripture, and argue that unless what Scripture says about itself and all things else of which it speaks is true, nothing is true. Unless God as an absolutely self-conscious person exists, no facts have any meaning. This holds not only for the resurrection of Christ, but for any other fact as well.”
