“The essence of happiness consists in an act of the intellect.”
(Thomas Aquinas, Summa Theologica) … What is implicit in this sentence? This is implicit: the fulfillment of existence takes place in the manner in which we become aware of reality; the whole energy of our being is ultimately directed toward attainment of insight. The perfectly happy person, the one whose thirst has been finally quenched, who has attained beatitude—this person is the one who sees. The happiness, the quenching, the perfection, consists in this seeing.

“The essence of a free government consists in an effectual control of rivalries.”
No. 13
1790s, Discourses on Davila (1790)
Context: Property must be secured, or liberty cannot exist. But if unlimited or unbalanced power of disposing property, be put into the hands of those who have no property, France will find, as we have found, the lamb committed to the custody of the wolf. In such a case, all the pathetic exhortations and addresses of the national assembly to the people, to respect property, will be regarded no more than the warbles of the songsters of the forest. The great art of law-giving consists in balancing the poor against the rich in the legislature, and in constituting the legislative a perfect balance against the executive power, at the same time that no individual or party can become its rival. The essence of a free government consists in an effectual control of rivalries. The executive and the legislative powers are natural rivals; and if each has not an effectual control over the other, the weaker will ever be the lamb in the paws of the wolf. The nation which will not adopt an equilibrium of power must adopt a despotism. There is no other alternative. Rivalries must be controlled, or they will throw all things into confusion; and there is nothing but despotism or a balance of power which can control them.

IV. That the species of myth are five, with examples of each.
On the Gods and the Cosmos
Context: Of myths some are theological, some physical, some psychic, and again some material, and some mixed from these last two. The theological are those myths which use no bodily form but contemplate the very essence of the Gods: e. g., Kronos swallowing his children. Since god is intellectual, and all intellect returns into itself, this myth expresses in allegory the essence of god.
Myths may be regarded physically when they express the activities of the Gods in the world: e. g., people before now have regarded Kronos as time, and calling the divisions of time his sons say that the sons are swallowed by the father.
The psychic way is to regard the activities of the soul itself; the soul's acts of thought, though they pass on to other objects, nevertheless remain inside their begetters.
The material and last is that which the Egyptians have mostly used, owing to their ignorance, believing material objects actually to be Gods, and so calling them: e. g., they call the earth Isis, moisture Osiris, heat Typhon, or again, water Kronos, the fruits of the earth Adonis, and wine Dionysus.
To say that these objects are sacred to the Gods, like various herbs and stones and animals, is possible to sensible men, but to say that they are Gods is the notion of madmen — except, perhaps, in the sense in which both the orb of the sun and the ray which comes from the orb are colloquially called "the sun".
