¶1Respondent herein,
¶21st: That respondent’s evidence in support of the charge of Mrs. Brown’s incompetency was so utterly inadequate as to amount to a failure of proof, thus entitling her to a directed verdict in her favor as a matter of law; hence, submission of that issue to the jury, no matter how improper the instructions may have been, was, in effect, a legal nullity on which no error can be predicated by respondent.
¶3We preface our discussion of this point by reminding counsel that in law, in busy courts, a proposition put forward less on faith than in hope is seldom entertained with charity. By application of that maxim we content ourselves with a one sentence summary of the nearly 1,500 pages of transcript accumulated in the six-day trial of this case. Respondent produced a score of witnesses to testify to Mrs. Brown’s incomprehensibly eccentric and sometimes violently irrational behavior, among them two accredited psychiatrists who gave it as their opinion from their examination of her that she was “a person of unsound mind . mentally ill;” that she had “a very disordered mind ... a persecution complex ... a paranoid psychosis . a mental illness of a severe nature” with “hypertension” adding to “her confusion” and aggravating “the tendency toward a paranoid condition;” that she might become “very dangerous” and was “in need of psychiatric treatment;” that she “needs to be under supervision;” that because of “her terribly disturbed mind” she “is incompetent to take care of herself” or “properly take care of her financial affairs,” because she is unable to “make the proper judgment on such matters;” and, finally, that “she is incompetent because of mental illness.” If our rejection of appellant’s argument on this point has unintended overtones of brusqueness, our apology is the welcome brevity of the analysis that prompts it.
¶42nd: That because respondent put Mrs. Brown on the stand as a part of his own case (as a sort of Exhibit A, one must suppose, since the result of the experiment leaves any other purpose to even more remote conjecture), he “vouched for and admitted that she was in fact competent and not of unsound mind” (having regard for § 491.060, RSMo 1969, V.A.M.S., which disqualifies persons of “unsound mind” as witnesses); hence, that respondent was precluded thereafter from offering proof of her ineompetency because, so the argument runs, to permit him to do so would be tantamount to allowing him to impeach his own witness by direct evidence.
¶5We find no precedent for that proposition.
¶6Implicit in the premise from which appellant’s argument proceeds is the assumption that a party, by calling his adversary as a witness, makes a judicial admission of his veracity which precludes the calling party from disputing anything he says. As shown above, the rule is otherwise. With an appropriate adjustment of the premise, then it is only a short step to the conclusion that respondent, by putting Mrs. Brown on the stand, did not unconditionally and ineluctably “admit that she was in fact competent and not of unsound mind” and was no more precluded from proving the contrary by other witnesses than is a party from proving the untruth of what his adversary says in similar circumstances. And so, despite the novel and ingenious reasoning that has gone into the proposition, the distinction of being the first court in the world to adopt it must, for us, be an opportunity lost.
¶73rd: That “Instruction No. 3 was a proper statement of the law,” nowise prejudicial to respondent.
¶8That brings us to the serious point in the case. We quote the instruction, and, to focus attention on the criticized part of it, we set out that part in italics:
¶9“Your verdict must be that Velma B. Brown is an incompetent person if you believe that at the time of these proceedings:
¶10First, Velma B. Brown has such a mental illness which renders her
¶11Second, by reason of such mental illness there is a total deprivation of her understanding, and
¶12Third, that her powers of reasoning and comprehension have been so far destroyed or reduced by such mental illness that she is incapable of knowing and appreciating the nature and consequences of her acts in respect to her own conduct and the management of her property.”
¶13*399For an orderly approach to the criticism leveled against the italicized portion of the instruction, it is necessary to refer back to the statute on this subject as it existed prior to 1955, § 458.010, RSMo 1949, since the cases relied on by appellant in defense of the instruction were all decided while that statute was in force. It read:
¶14“For the purposes of this article, wherever the words ‘person of unsound mind’ or ‘insane person’ occur therein, said words shall be construed to mean either an idiot, or a lunatic, or a person of unsound mind and incapable of managing his own affairs, as the case may be, upon proof as aforesaid.”
¶15It will be seen that statute equated persons of unsound mind with insane persons by applying the same alternative definitions to each; hence, conversely for illustration, for a person to be adjudged “of unsound mind and incapable of managing his own affairs,” the degree of his derangement must be shown to be such as would cause him to be classified as an insane person. In the first case on the subject, Harrelson v. Flournoy, 229 Mo.App. 582, 589-90, 78 S.W.2d 895, 899 (1934), the court took that view, saying that “unless they [weak minds] betray a total lack of understanding or idiocy or delusion, they cannot properly be considered unsound.” (Emphasis ours). That case, at the same local citation, explains the philosophy of the law in the light of the statute that suggested it by saying, “To establish any standard of intellect or information, beyond the possession of reason in its lowest degree, as in itself essential for legal capacity, would create endless uncertainty, difficulty, and litigation, would shake the security of property, and wrest from the aged and infirm that authority over their earnings and savings which is often their best security against injury and neglect.” (Emphasis ours).
¶16But the old statute was repealed in 1955 and a new one enacted, § 475.010, RSMo 1969, V.A.M.S., which reads:
¶17“When used in sections 475.010 to 475.370, unless otherwise apparent from the context: … (3) An ‘incompetent’ is any person who is incapable by reason of insanity, mental illness, imbecility, idiocy, senility, habitual drunkenness, excessive use of drugs, or other incapacity, of either managing his property or caring for himself or both.”
¶18Did the new statute change the law? We say it did, for these reasons:
¶19Of arresting significance is the fact that nowhere does the new statute use the term “insane person,” or “person of unsound mind” as a synonym for it. Since those terms, as interpreted by the courts in the cases cited above, were of controlling im*400portance in fixing the law’s standard of mental incapacity under the old statute, there must have been some reason for their omission from the new one. And we think Judge Ruark put his finger on it when he said that we live in a time of “changing concepts in respect to mental illness” and “[o]ur legislature has recognized this by the use of the word ‘incompetent’ in the statute, and by the definition of an incompetent as encompassing various mental disabilities, including that of ‘insanity.’ ” State v. England, 328 S.W.2d 732, 736 (Mo.App.1959) (Emphasis his).
¶20We have only to consult the legislative history of the Act (which we are authorized to do, St. Louis Southwestern Ry. Co. v. Loeb, 318 S.W.2d 246, 252 (Mo. banc 1958)) to confirm that view. In the committee comment, appended beneath the text of the statute in 26A V.A.M.S. at 6, we read:
¶21“The definition of ‘incompetent’ as here given is designed to make possible the use of that term instead of ‘insane person’ and to cover all persons of unsound mind, whether insane or not.” (Emphasis ours).
¶22Clearly it was the purpose of the legisla-. ture, in enacting the new statute, to fix a more flexible standard of mental incapacity and to relegate to past history any concept of incompetency which is circumscribed by the requirements of the earlier cases, and particularly that most stringent one, that to be adjudged mentally incompetent one must be shown to have suffered “a total deprivation of understanding.”
¶23The order is affirmed and the cause remanded.
¶24All concur.
¶25. Respondent is identified as David Bruce Adamson, Chairman of the Board and President of the First National Bank of Joplin, Missouri.
¶26. For a review of the authorities from other jurisdictions approving the practice complained of here and giving the reasons therefore, see Annot., 22 A.L.R.2d 756 (1952).
¶27. Were the rule otherwise, the calling party would put himself at the mercy of his opponent, at ransom to the dirk of falsehood, a result no statute or rule of law was ever designed to invite.
¶28. Disregard the inelegant syntax; it is not “such as which” will affect our decision.
¶29. A bit of background is appropriate in fairness to the trial judge. There is no M.A.I. pattern for an instruction on this subject (an omission that every trial judge is familiar with in cases involving issues of more complexity, say, than automobile accidents). Confronted with that frustration, counsel for respondent made up one which closely parallels Instruction No. 3 except it omits all reference to the proposition submitted in the italicized portion of that instruction. Counsel for appellant were understandably insistent on a more restrictive standard of mental incompetency for the jury’s guidance *399and, by dint of the cases discussed later in the body of this opinion and in the absence of other authority, persuaded the court, in the heat and haste of the emergency, to add the italicized part and give the instruction, as so amended, as the court’s own instruction. These things happen in these circumstances with distressing frequency, and it would be ungracious of us not to acknowledge our sympathy with the trial judge in the exigency that confronted him.
¶30. Lawyers of mature experience will realize that a certain amount of flatulent rhetoric has gone into that pronouncement, and a good deal of empirical knowledge has been neglected by it.
¶31. If “a total lack of understanding” is not the hallmark of slavering idiocy, it is, by popular comprehension, the next thing to it. Even an unweaned infant has some degree of understanding! What court can be expected to say, in the light of the new statute, that “an ‘incompetent’ is any person who is incapable … of either managing his property or caring for himself’ only when his mental capacity is shown to be less than that of a diapered child?
