{Footnote 1} The truths of doctrine of the church derived from the Word must be the starting-point, and these must first be acknowledged, and afterwards it is permissible to consult knowledges (n. 6047).  Thus it is permissible for those that are in an affirmative state towards the truths of faith to confirm them rationally by knowledges, but it is not permissible for those who are in a negative state (n. 2568, 2588, 4760, 6047).  It is in accordance with Divine order to enter rationally from spiritual truths into knowledges, which are natural truths, but not to enter from the latter into the former, because spiritual influx into natural things is possible, but not natural or physical influx into spiritual things (n. 3219, 5119, 5259, 5427, 5428, 5478, 6322, 9109, 9110).

456.  That the spirit of man, when it has been loosed from the body, is still a man and in a like form, has been proved to me by the daily experience of many years; for I have seen such and have listened to them a thousand times, and have talked with them about this fact, that men in the world do not believe them to be men, and that those that do believe this are regarded by the learned as simple.  Spirits are grieved at heart that such ignorance still continues in the world, and above all within the church. [2] But this belief they said had emanated chiefly from the learned, who had thought about the soul from ideas derived from bodily sense; and from such ideas the only conception they formed of the soul was as being mere thought; and when this is regarded apart from any subject as its containant and source it is merely a fleeting breath of pure ether that must needs be dissipated when the body dies.  But as the church believes from the Word in the immortality of the soul they are compelled to ascribe to it something vital, such as pertains to thought, but they deny to it any thing of sense, such as man possesses, until it has again been joined to the body.  On this opinion the doctrine in regard to the resurrection is based, with the belief that the soul and body will be joined again at the time of the final judgment.  For this reason when any one thinks about the soul in accordance with this doctrine and these conjectures, he has no conception that it is a spirit, and in a human form.  And still further, scarcely any one at this day knows what the spiritual is, and still less that spiritual beings, as all spirits and angels are, have any human form. [3] Consequently, nearly all that go from this world are greatly surprised to find that they are alive, and are as much men as before, that they see, hear, and speak, and that their body enjoys the sense of touch as before, with no difference whatever (see above, n. 74).  And when they cease to be astonished at themselves they are astonished that the church should know nothing about this state of men after death, thus nothing about heaven or hell, when in fact all that have ever lived in the world are in the other life
