The position and aspects of the Moon and Mercury are therefore to be considered in making judgment of the mental endowments and disposition of the subject.
Planets that are in conjunction or aspect to either the Moon or Mercury will impress their nature strongly on the character and disposition. The natures of the planets have already been recited ([Sect. I., chap. i.]), and it is therefore only necessary to consider further, in this connection, the nature of the aspect that is thrown to the Mental Significators by the other bodies. Thus the Sun being in trine to the Moon will give a proper degree of independence and dignity, while the square aspect or opposition of the Sun would indicate an excess of pride, harmful to the subject in his ordinary relationships. In the same manner, the good aspect of Jupiter would show benevolence and regulated philanthropy, while the opposition or other evil aspect of the same body would indicate extravagance and ostentatious display of charity.
The good and bad aspects of the planets may be summed up in a few lines as follows:—
| IN GOOD ASPECT. | IN EVIL ASPECT. |
| Neptune—Genius, inspiration. | Insanity, obsession. |
| Uranus—Originality, invention. | Obstinacy, eccentricity. |
| Saturn—Steadfastness, fidelity. | Deceitfulness, suspicion. |
| Jupiter—Benevolence, joviality. | Ostentation, profligacy. |
| Mars—Energy, executiveness. | Impulse, destructiveness. |
| Sun—Dignity, independence. | Vanity, egotism. |
| Venus—Affability, art. | Self-indulgence, disorderliness. |
| Mercury—Alertness, ingenuity. | Inquisitiveness, meddling. |
| Moon—Grace, idealism. | Inconstancy, awkwardness. |
The general trend of the disposition and habit of mind is judged by the position of the majority of the planets, according to the “Constitution” of the Signs they occupy. Thus, the majority of the planets being in—
Cardinal or Movable Signs indicates executive ability, business aptitude, pioneer spirit, ambition, capability to cut out a line in life for oneself, and to make headway against difficulties. Such persons are usually the foremost in their particular sphere of life, and are always found in the most progressive movements, reforms, &c.
Fixed Signs—Stability, patience, endurance, method, caution, and diplomacy. Such persons are apt to become the originators of schools of thought, policies, and schemes. They have fixity of purpose, determination, independence, and pivotal stability. They sit still and the world revolves around them.
Flexed or Common Signs—Versatility, flexibility, suavity, adaptability, and lack of originality. Such people usually have too many irons in the fire, and take in hand more than they can bring to satisfactory conclusion. This is due to their versatility. They have a superficial knowledge of many things, but lack the persistence to bring that knowledge to practical effect. At the same time their adaptability is the occasion of many successes in life, and their agreeableness, sympathy, and suavity create many friends for them.
In the Wheel of Life the cardinal signs denote the rim or tyre which is ever on the move, having the greatest acceleration. The Common Signs represent the spokes of the wheel, uniting the tyre to the nave, and in that sense representing the power of adaptability. The Fixed Signs represent the nave, which remains quiescent and still, being useful by that pivotal stability and apparent non-entity.
Thus, while the Sign-groupings of the planets are useful in giving the keynote of the nature and disposition, the particular faculties and characteristics are to be judged only from the aspects of the planets to the Moon and Mercury. Further, it will be noted that those planets which occupy the 3rd and 9th Houses, and those also which are just rising at the moment of birth, will strongly impress themselves on the nature, apart from any aspects they may hold to the Mental Rulers. This is on account of the natural relationship of those Houses to the mind and its means of expression.
