Thomas Aquinas

“ Now it is impossible for agent to overcome patient except through the weakening of the hold which the form of the patient has over its matter, if we speak of the passion which is against nature, for it is of passion in this sense that we are speaking now: for matter is not subject to one of two contraries, except through the cessation or at least the diminution of the hold which the other contrary has on it. Now the human body and all that it contains will be perfectly subject to the rational soul, even as the soul will be perfectly subject to God. ”

“ Hence we do not say that madmen or other witless persons (in whom there is this kind of outflow of species towards the organs of sense, on account of the powerful influence of the imagination) have real sensations, but that it seems to them that they have sensations. Consequently we must say with others that sensation in glorified bodies will result from the reception of things outside the soul. It must, however, be observed that the organs of sense are transmuted by things outside the soul in two ways. ”

“ The more perfect the sense the less does it require to be altered in order to perceive its object. Now the smaller the angle at which the sight is affected by the visible object, the less is the organ altered. Hence it is that a stronger sight can see from a distance more than a weaker sight; because the greater the distance the smaller the angle at which a thing is seen. ”

“ Wherefore if the saints, in the resurrection, were to have sensations by emitting and not by receiving species, sense in them would be not a passive but an active power, and thus it would not be the same specifically with sense as it is now, but would be some other power bestowed on them; for just as matter never becomes form, so a passive power never becomes active. ”

“ Hence an immoderate movement of the heart is called its passion, but a moderate movement is called its operation. The reason of this is that whatever is patient is drawn to the bounds of the agent, since the agent assimilates the patient to itself, so that, therefore, the patient as such is drawn beyond its own bounds within which it was confined. Accordingly taking passion in its proper sense there will be no potentiality to passion in the bodies of the saints after resurrection ”

“ The fact that the image of an object placed in opposition to a mirror directly opposite the sun's rays does not appear therein, is not due to the reception being hindered, but to the hindering of reflection: because for an image to appear in a mirror it must needs be thrown back by an opaque body, for which reason lead is affixed to the glass in a mirror. The sun's ray dispels this opacity so that no image can appear in the mirror. But the clarity of a glorified body does not destroy the diaphanous nature of the pupil, since glory does not destroy nature ”

“ As already explained, by this passion that takes place in actual sensation and is no other than the aforesaid reception of species, the body is not drawn away from natural quality, but is perfected by a spiritual change. Wherefore the impassibility of glorified bodies does not exclude this kind of passion.
Reply to Objection 2: Every subject of passion receives the action of the agent according to its mode. ”

“ And again, a heavenly nature cannot exercise such power over the human body as to take from it its elemental nature which is passible by reason of its essential constituents. Consequently we must say otherwise that all passion results from the agent overcoming the patient, else it would not draw it to its own bounds. ”

“ Wherefore the body of an animal has, through its tangible qualities according to the present state of life, a natural aptitude to be affected with a natural and spiritual alteration by the object of touch. ”

“ Consequently others say that the senses will be actualized by receiving species, not indeed from external sensibles, but by an outflow from the higher powers, so that as now the higher powers receive from the lower, so on the contrary the lower powers will then receive from the higher. But this mode of reception does not result in real sensation, because every passive power, according to its specific nature, is determined to some special active principle, since a power as such bears relation to that with respect to which it is said to be the power. ”

“ For this reason the touch is said to be the most material of the senses, since it has a greater measure of material alteration connected with it. Yet material alteration is only accidentally related to the act of sensation which is effected by a spiritual alteration. Consequently the glorified bodies, which by reason of their impassibility are immune from natural alteration, will be subject only to spiritual alteration by tangible qualities. ”

“ The elemental qualities are the instruments of the soul, as stated in De Anima ii, text. 38, seqq., for the heat of fire in an animal's body is directed in the act of nutrition by the soul's power. When, however, the principal agent is perfect, and there is no defect in the instrument, no action proceeds from the instrument, except in accordance with the disposition of the principal agent. ”

“ Whenever a thing is seen at an angle, the angle must be proportionate to the distance of the object seen: because what is seen from a greater distance is less seen and at a lesser angle, so that the angle may be so small that nothing is seen of the object. ”

“ If however a thing be naturally adapted to be altered only with a spiritual alteration it does not follow that it is altered naturally. For instance the air is not receptive of color, according to its natural being, but only according to its spiritual being, wherefore in this way alone is it altered: whereas, on the contrary, inanimate bodies are altered by sensible qualities only naturally and not spiritually. ”

“ Wherefore since the proper active principle in external sensation is a thing existing outside the soul and not an intention thereof existing in the imagination or reason, if the organ of sense be not moved by external things, but by the imagination or other higher powers, there will be no true sensation. ”

“ When one of two things is the type of the other, the attention of the soul to the one does not hinder or lessen its attention to the other: thus a physician while considering urine is not less but more able to bear in mind the rules of his art concerning the colors of urine. And since God is apprehended by the saints as the type of all things that will be done or known by them, their attention to perceiving sensibles, or to contemplating or doing anything else will nowise hinder their contemplation of God, nor conversely. ”

“ Secondly, by a spiritual transmutation, as when a sensible quality is received in an instrument, according to a spiritual mode of being, when, namely, the species or the intention of a quality, and not the quality itself is received: thus the pupil receives the species of whiteness and yet does not itself become white. Accordingly the first reception does not cause sensation, properly speaking, because the senses are receptive of species in matter but without matter. ”

“ Further, when the act of one of the soul's powers is intense, the acts of the other powers are remiss. Now the soul will be supremely intent on the act of the contemplative power in contemplating God. Therefore the soul will have no actual sensation whatever. ”

“ First in a broad sense, and thus every reception is called a passion, whether the thing received be fitting to the receiver and perfect it, or contrary to it and corrupt it. The glorious bodies are not said to be impassible by the removal of this kind of passion, since nothing pertaining to perfection is to be removed from them. ”

“ Hence "mortal" is put in the definition of man, not as though mortality were essential to man, but because that which causes passibility and mortality in the present state of life, namely composition of contraries, is essential to man, but it will not cause it then, on account of the triumph of the soul over the body.
Reply to Objection 2: Potentiality is twofold, tied and free: and this is true not only of active but also of passive potentiality. ”

“ First by a natural transmutation, when namely the organ is disposed by the same natural quality as the thing outside the soul which acts on that organ: for instance, when the hand is heated by touching a hot object, or becomes fragrant through contact with a fragrant object. ”

“ Moreover, according to this, impassibility could not be one of their gifts, because it would not imply a disposition in the impassible substance, but merely an external preventive to passion, namely the power of God, which might produce the same effect in a human body even in this state of life. ”

“ Further, nothing will be corrupted after the resurrection because the whole creature will be invested with a certain virtue of incorruption. Now the sense of smell cannot have its act without some corruption having taken place, because smell is not perceived without a volatile evaporation consisting in a certain dissolution. ”

“ Since then there will be certain actual defects in the bodies of the blessed, such as the scars of the wounds in the martyrs, even as they were in Christ, it would seem that their perfections will not suffer, if we grant their bodies to be passible. ”

“ That some evaporation should be necessary is due to the fact that smell in bodies is mixed with humidity; wherefore it is necessary for dissolution to take place in order for the smell to be perceived. ”
