10071. 'And the tail' means all truth there. This is clear from the meaning of 'the ram's tail' as truth. 'The tail' means truth because it comes last, and truth resides in last or lowest things, 9959a. The tail is also the last part of the cerebrum and cerebellum, for these extend into the spinal cord, and this also terminates in the tail, which is for that reason the appendage at the end of all three. Therefore Lev.3:9 says that in sacrifices the tail should be removed next to the backbone. The fact that 'the tail' means truth in last or lowest things, and in the contrary sense falsity, is clear from the following places: In Isaiah,
Jehovah will cut off from Israel head and tail. The old and the honourable [in face] is the head, but the prophet, the teacher of a lie, is the tail. Isa 9:14,15.
In the spiritual sense 'cutting off head and tail' means severing good and truth; for the subject is the Church, and when this has been laid waste 'the head' means evil and 'the tail' falsity. 'The head' means good, see 4938, 4939, 5328, 9913, 9914, as does 'the old', 6524, 9404; and 'the prophet' means a teacher of truth, and so in the abstract sense [without reference to persons] truth itself, 2534, 7269. In the contrary sense therefore 'the head' means evil, as do 'the old' and 'the honourable' who will perform it, while 'the tail' means falsity, as does 'the prophet', who is for that reason called 'the prophet of a lie'; for 'a lie' means falsity. In the same prophet,
There will not be for Egypt [any] work which the head and tail may do. Isa 19:15.
'Egypt' stands for those who, desiring to enter into the truths and forms of the good of faith, use reasonings based on factual knowledge, and not on revealed truths, thus not on belief in these, 1164, 1165, 1186. The lack of 'work which the head and tail may do' stands for the fact that they have neither good nor truth. The fact that 'the tail' means truth in last or lowest things is evident from its meaning in the contrary sense, in which 'the tail' means falsity. In John,
The locusts had tails like scorpions, and stings were in their tails, and they had power to harm people. Rev 9:10.
'Tails like scorpions, and stings in their tails' are cunning reasonings based on falsities which they use to convince and thereby damage someone, which is why it says that they had power to harm people. Furthermore falsity in outermost things is meant by 'locust', see 7643. In the same book,
The horses' tails were like serpents, having heads; and by means of them they do harm. Rev 9:19.
'Tails like serpents' here also stands for reasonings based on falsities which are used to cause harm. In the same book,
The dragon's tail drew a third part of the stars of heaven, and cast them down to the earth. Rev 12:4.
'The dragon's tail' stands for truths that have been falsified, in particular through the application of them to evils; 'the stars' are cognitions or knowledge of truth and good which has been falsified; and 'casting them down to the earth' means destroying them.
