(Note: this is a collection of the meanings attributed to the cards by some occultists in the past centuries. It does not reflect my own study or opinion of the cards. It is only meant as a quick comparative reference as I develop my own take.)

Paul Foster Case (and Ann Davies)

The time period is the third decanate of Aquarius, February 9 to 18, under the rulership of Venus.
Well-Dignified: partial success; the Querent is too easy-going or does not draw sufficiently on his reserve force; he has good opportunities but may not make the most of them; he is likely to compromise too easily.
Ill-Dignified: love of ease and display cause loss; the Querent suffers from the insolence of others and may be insolent himself; there is danger that his own confidence may be betrayed, or that he may be led into betraying the confidence of others.
Keyword: Instability.
(From the Oracle of Tarot course)

A. E. Waite

A man in the act of carrying away five swords rapidly; the two others of the card remain stuck in the ground. A camp is close at hand. Divinatory Meanings: Design, attempt, wish, hope, confidence; also quarrelling, a plan that may fail, annoyance. The design is uncertain in its import, because the significations are widely at variance with each other. Reversed: Good advice, counsel, instruction, slander, babbling.

Aleister Crowley

The Seven of Swords is called Futility. This is a yet weaker card than the Seven of Wands. It has a passive sign instead of an active one, a passive planet instead of an active one. It is like a rheumatic boxer trying to “come back” after being out of the ring for years. Its ruler is the Moon. The little energy that it possesses is no more than dream-work; it is quite incapable of the sustained labour which alone, bar miracles, can bring any endeavour to fruition. The comparison with the Seven of Wands is most instructive.

Netzach, in the suit of Swords, does not represent such catastrophe as in the other suits, for Netzach, the Sephira of Venus, means victory. There is, therefore, a modifying influence; and this is accentuated by the celestial rule of the Moon in Aquarius.

The intellectual wreckage of the card is thus not so vehement as in the Five. There is vacillation, a wish to compromise, a certain toleration. But, in certain circumstances, the results may be more disastrous than ever. This naturally depends upon the success of the policy. This is always in doubt as long as there exist violent, uncompromising forces which take it as a natural prey.

This card, like the Four, suggests the policy of appeasement. The symbol shows six Swords with their hilts in crescent formation. Their points meet below the centre of the card, impinging upon a blade of a much larger up-thrusting sword, as if there were a contest between the many feeble and the one strong. He strives in vain.
(From the Book of Thoth)

Golden Dawn’s Book T

TWO Angelic Radiating Hands as before, each holding three swords. A third hand holds up a single sword in the centre. The points of all the swords “just touch” each other, the central sword not altogether dividing them.
The Rose of the previous symbols of this suit is held up by the same hand which holds the central sword: as if the victory were at its disposal. Symbols of Moon and Aquarius.

Partial success. Yielding when victory is within grasp, as if the last reserves of strength were used up. Inclination to lose when on the point of gaining, through not continuing the effort. Love of abundance, fascinated by display, given to compliments, affronts and insolences, and to spy upon others. Inclined to betray confidences, not always intentionally. Rather vacillatory and unreliable.
