¶2The defendant was convicted in the circuit court of Mu-ltnomah County of the crime of murder in the first degree in killing one Gus' Barry on the morning of the fifteenth of January, eighteen hundred and ninety-three, by shooting him with a pistol. The proof shows that previous to the homicide, the deceased, with his wife and Miss Wright, his sister-in-law, lived in a building in the city of Portland fronting upon and abutting Olay Street, containing three rooms, the one in front being occupied by the deceased and wife as a bedroom, immediately in the rear of which was the sitting-room, connecting with this room by double doors. In the rear of the sitting-room was another room, occupied by Miss Wright as a bedroom. The prisoner, who seems to have been a suitor of Miss Wright, was requested by her, two or three days before the homicide, at the suggestion of Mrs. Barry, to come and stay at the house nights, because the deceased *243was' drinking, and it was feared he might assault and beat his wife, as he sometimes did when under the influence of liquor. On the night of the homicide the prisoner went to the house about half-past twelve or one o’clock in the morning, passing in from the street through an alleyway to the rear door, where he was admitted by Miss Wright, of whom he inquired if deceased was in, and, being answered in the negative, said, “ I will see for myself.” He then walked through the hall and across the sittingroom to the door of the bedroom of deceased and wife, who were both in bed, opened the door, and immediately thereafter the shooting occurred. It is disclosed from the defendant’s own testimony that up to the time he entered the room of the deceased nothing had occurred to arouse his passion or disturb his mind in any way. There is some slight variance between the evidence for the state and the defense as to what occurred after the prisoner entered the room, but it is of no consequence on this appeal. The court instructed the jury fully upon the various aspects of the case, and in so doing defined particularly and with care the deliberation and premeditation necessary to constitute murder in the first degree.
¶3A short time after the cause was submitted, the jury returned into court, and through their foreman asked the following question: “Would the time which elapsed wdnle the defendant was going from the sidewalk into the room where the shooting took place be sufficient to give opportunity for deliberation and premeditation?” to which the court answered, “It would.” This is the principal assignment of error relied upon for the reversal of the judgment. The contention for the defendant is that,while no particular time is necessary for deliberation and premeditation, it was an invasion by the court of the province of the jury to tell them, as a matter of law, *244under the facts of this particular case, that any fixed time would suffice for deliberation and premeditation on the part of the defendant. The argument is that while, as a conclusion of fact, the time occupied by the defendant in passing from the sidewalk to the room of the deceased may have afforded him sufficient time for deliberation and premeditation, although but a few moments elapsed, yet it cannot be so assumed as a matter of law, because its determination was peculiarly within the province of the jury under the evidence.
¶4The crime of murder-in the first degree is defined by the statute to be the killing of a human being “ purposely and of deliberate and premeditated malice.” To constitute this crime, it is essential that the deliberate and premeditated design to kill must precede the killing by some appreciable length of time, sufficient for reflection and consideration upon the matter, and the formation of a definite purpose to kill, and it matters not how short the lime is if it is sufficient for that purpose. The rapidity of mental action is such that the formation of a design may not occupy more than a moment of time, and it is sufficient if it is formed and matured while the mifid is in its normal state, and under the control of the slayer, however brief the space of time may be. In this case it • affirmatively appears from all the evidence, both of the state and that of the prisoner himself, that during the time he was going from the sidewalk into the room of the deceased he was in possession of his usual faculties, and his mind was in its normal state, uninfluenced by passion or disturbed by any sudden and uncontrollable emotions, and under such circumstances we think it was not error to declare as a matter, of law that the time occupied in so doing gave him opportunity for deliberation and premeditation, and this is all the court declares in its answer to the question propounded by the jury. *245The question did not call for, nor did the court by its answer intimate, any opinion as to whether there was deliberation and premeditation, but only that the time which elapsed after the defendant left the sidewalk was sufficient to give him as a sane man in a calm and deliberate state of mind, as the evidence shows him to have been, an opportunity sufficient for that purpose, leaving the question as to whether there was deliberation and premeditation for the jury to determine under the law as previously given them. Each of the other assignments of error have been carefully examined, but finding no error in the record we have no alternative but to affirm the judgment.

¶12The contention of defendant’s counsel, and the principle embodied in the instructions refused, as well as those given, to which the exception is directed, as we understand it, is that the real or apparent danger, sufficient to justify the taking of human life, is to be determined from the defendant’s standpoint alone, and that if he honestly believed his life in danger, or that he was in .danger of great bodily harm, and, acting under such belief, took the life of his supposed assailant, it would be excusable homicide. This theory bases the right of .self-defense upon the belief of the person defending, and not upon the ground of such belief or the reasonable appearance of danger. We do not so understand the law. A recent writer on this subject has thus concisely stated the rule as supported by the great weight of authority: “In order to justify a homicide on the ground that it was committed in self-defense, it must appear that the defendant, at the time he caused the death of the deceased, was acting under a reasonable belief that he was in imminent danger of death or great bodily harm from the deceased, and that it was necessary for him to strike the fatal blow or to perform such other act causing the death of deceased, in order to avoid the death or great bodily harm which was apparently imminent”: Kerr on Homicide, § 166, and authorities there cited. Under this rule and the authorities cited in its support the justification of a homicide on the ground of self-defense is not a question which depends wholly upon the belief which the defendant entertained, but the question is what was his belief, and whether, under all the circumstances, as they appeared to him at the time of the homicide, the jury think there was ground for a reasonable belief in his mind *251that he was in clanger of death or great bodily harm Mr. Wharton advocates the doctrine that the question of apparent necessity is to be determined from the defendant’s standpoint, but he says that it is only a non-negligent belief in danger which will be an excuse for a homicide committed under such fear: 1 Wharton, Critn. Law, 9th Ed. 490; 14 Central Law Journal, 263. If this is anything more than stating in another form that it must be a reasonable belief, we prefer to follow the path as marked out by the great weight of authority. A man, though in no apparent danger, might kill another through fear, alarm, or cowardice, under the belief, honestly entertained, that great bodily harm is about to be inflicted upon him, and certainly it could not be claimed that under such circumstances he would be justified in so doing, because the belief would be an unreasonable one and not justified by the circumstances in which he was placed. The right of self-defense is founded on the law of necessity, and can only be exercised when the slayer is acting under a reasonable belief, arising from the circumstances of the case as they appear to him, that his life is in imminent danger or that he is in danger of great bodily harm from some overt act of his assailant, and that it is necessary for him to take life to protect his own. The reasonableness of the- defendant’s belief was to be determined from, his standpoint, but it was a question for the jury, as to whether he had sufficient grounds upon which to base such belief. As we understand it, the charge of the court above quoted is in conformity to this principle, and was, therefore, free from objection. By the expression, “actual or real danger to the defendant’s comprehension as a reasonable man,” as used in the charge, which is the only portion objected to, the court did not, as counsel seems to claim, lay down the rule that defendant’s conduct was to be judged by the *252standard of an “ideal reasonable man,” but only that he must have acted under a reasonable belief in apparent danger, justified by the circumstances of the case. This is obvious from the remainder of the instruction, especially from whatimmediately follows, which is explanatory thereof. We conclude, therefore, that there was no error in refusing the instruction asked, or in that given by the court.

¶14In State v. Keene, 50 Mo. 360, from which a portion of the instruction objected to was evidently taken, Mr. Justice Wagner says: “When the homicide is committed under such circumstances that it is doubtful whether the *254act was committed maliciously, or from a well-grounded apprehension of danger, it is very proper that the jury should consider the fact that the deceased was turbulent, violent, and desperate, in determining whether the accused had reasonable cause to apprehend great personal injury to himself.” And in People v. Murray, 10 Cal. 310, from which the remainder was taken, it is said: “The rule is well settled that the reputation of the deceased cannot be given ' in evidence, unless at the least the circumstances of the case raise a doubt in regard to the question whether the prisoner acted in self-defense. It is no excuse for a murder that the person murdered was a bad man; but it has been held that the reputation of the deceased may sometimes be given in proof to show that the defendant was justified in believing himself in danger, when the circumstances of the contest are equivocal.” In State v. Bryant, 55 Mo. 78, in considering this question, Mr. Justice Wagner further says: “ Whilst it is perfectly true that the character of the deceased affords no justification, and will not even palliate the crime, where it appears that the defendant was the aggressor, and provoked the altercation, still it frequently becomes of great importance in determining the degree and quality of the offense. A bad man, as well as a good one, is equally under the protection of the law, but in a case of homicide, where it is doubtful whether it was committed with malice or from a well-grounded apprehension of danger, it is necessary to take into consideration the fact that the deceased was desperate, violent, or dangerous. A peaceable, well-disposed man, although in anger, might excite very little fear, whilst the menacing attitude of a cruel, vindictive, and desperate person would cause the greatest apprehension, and justify a line of action in the one case which would be wholly unwarrantable in the other.”
¶15The theory upon which evidence of this nature is *255admissible in cases of homicide, is that when the plea of self-defense is interposed, a danger which is apparently imminent is to be considered and treated as if it were actual, real, and imminent, and such apparent danger must necessarily appear more menacing when regarded with reference to the assailant’s character for violence and brutality as well as his special animus to the accused. When, therefore, the evidence tends to show that the defendant acted under an honest apprehension of danger from some overt act of the deceased, he may put in evidence the ferocity, brutality, or vindictiveness of his assailant as tending to show that he had reasonable ground for such belief, and when the acts or intentions of the deceased in reference to the fatal encounter are equivocal or doubtful, such evidence becomes very important and material. But before it can be introduced, or considered by a jury, the testimony must at least tend to show that the defendant was assailed by the deceased, and in apparent danger, for the character of the deceased, however bad, will not of itself justify or even palliate the crime. We think there was no error in giving the instruction complained of, and that the court did not, as claimed by counsel, prohibit the jury from considering the evidence of deceased’s character, unless they were in doubt as to his guilt or innocence, but in effect the instruction was, that if the jury were in doubt as to whether the killing was malicious or from well-grounded apprehension of danger, it was proper to consider such testimony as tending to show that his act was not malicious, but founded on a reasonable belief in imminent peril.

¶17The utmost confusion exists in the adjudged cases in this matter of definition, and instances abound in the books where the same definition has been held error in one jurisdiction and as correct in another, and this is even true in the same state. But the authorities all agree that a doubt, to be reasonable, must be actual and substantial, as contradistinguished from a mere vague and imaginary one, but they differ widely as to what is an accurate expression of the definition of such a doubt. This difference naturally grows out of the inadequacy of language to make plainer, by further definition or refining, a term the meaning of which is within the comprehension of every person capable of understanding common English. It would undoubtedly have been better and safer for the trial court in this case to have omitted from its definition that portion of the instruction to which the objection was directed, but, since it was given, we must decide whether it contained error prejudicial to the defendant’ In Cowan v. State, 22 Neb. 519, 35 N. W. 405, and Carr v. State, 23 Neb. 749, 37 N. W. 630, it was held that an instruction defining a reasonable doubt as “a doubt for having which the jury can give a reason based upon the testimony,” was reversible error, because it was calculated to and did mislead and confuse *258the jury, but just how is not stated, unless, as can be inferred from the doctrine of the case of Brown v. State, 105 Ind. 385, 5 N. E. 500, cited in' the opinion in Carr v. State, it was because the court limited the doubt to one arising from the evidence alone, (which is not so limited in the case at bar,) and which in the case referred to was criticised because such a doubt might arise from the want of evidence as well as from the evidence in the case, although it was held not reversible error. These Nebraska cases are the only ones to which our attention has been called or which we have been able to find in which such an instruction has been held error, except one from Alabama,—State v. Ray, 50 Ala. 104,—which is in direct conflict with the succeeding case reported in the same volume. In Morgan v. State, 48 Ohio St. 371, 27 N. E. 710, and in State v. Sauer, 38 Minn. 438, 38 N. W. 355, instructions substantially the same were criticised because they did not define, but themselves required definition, which might truthfully be said of any definition of a reasonable doubt heretofore given. But the objection did not in either case seem to impress the court as of any great importance.
¶18In People v. Stoubenvoll, 62 Mich. 329, 28 N. W. 883, it seems to be conceded that the instruction that “what is meant by a reasonable doubt is, as the term implies, a doubt arising out of the facts and circumstances of the case,- in maintaining which you can give a good reason,” was not strictly accurate, but the court said it could have produced no practical consequences in the case, and refused to reverse on that ground. In 14 Central Law Journal, 447, it is said that a reasonable doubt “must be such that a jury can give a reason for,” and Judge Speer, in instructing the jury in the case of U. S. v. Jackson, 29 Fed. R. 503, and in U. S. v. Jones, 31 Fed. R. 718, says that “it is a doubt for which a good reason can *259be given, which reason must be based on the evidence or want of evidence.” So also in People v. Guidici, 100 N. Y. 503, 3 N. E. 493, which was an appeal from a conviction of murder in the first degree, the court held, that an instruction that a reasonable doubt was one “ for which some good reason arising from the evidence can be given” was not error, and affirmed the judgment. In the course of the opinion Mr. Justice Daneorth says that it has not been too strongly stated that all the authorities agree that “an undefinable doubt which cannot be stated, with the reason upon which it rests so that it may be examined and discussed, can hardly be considered a reasonable doubt, as such an one would render administration of justice impracticable”: 3 Greenleaf, Ev. § 29, note, 14th Ed. And this, it seems to us, is in substance what the-court said in the language complained of when read with the whole instruction of which it forms a part, and when so read it was evidently the result of a struggle by the-court to so define the term as to enable the jury to distinguish a reasonable doubt from some vague and imaginary one. The particular language in question may be, and no doubt is, subject to the criticism that it does not define, but needs defining, but we do not think it could have misled or perplexed the jury when considered in connection with the remainder of the instruction. If every criminal case is to be reversed for some technical inaccuracy in the definition of a reasonable doubt, then indeed the “administration of justice becomes impracticable.” Fully realizing the consequences of this decision, we have given the question presented the utmost care, and, finding no error in the record, have no alternative but to adhere to our former opinion.
