“The good is the everlasting, the pinnacle of our life. … life is striving towards the good, toward God. The good is the most basic idea … an idea not definable by reason … yet is the postulate from which all else follows.”

Original: (el) εἰ οὖν οὕτως εὖ ἔχει, ὡς ἡμεῖς ποτέ, ὁ θεὸς ἀεί, θαυμαστόν: εἰ δὲ μᾶλλον, ἔτι θαυμασιώτερον. ἔχει δὲ ὧδε. καὶ ζωὴ δέ γε ὑπάρχει: ἡ γὰρ νοῦ ἐνέργεια ζωή, ἐκεῖνος δὲ ἡ ἐνέργεια: ἐνέργεια δὲ ἡ καθ᾽ αὑτὴν ἐκείνου ζωὴ ἀρίστη καὶ ἀΐδιος.

Essays in Criticism, second series (1888)
Context: If what distinguishes the greatest poets is their powerful and profound application of ideas to life, which surely no good critic will deny, then to prefix to the word ideas here the term moral makes hardly any difference, because human life itself is in so preponderating a degree moral.
It is important, therefore, to hold fast to this: that poetry is at bottom a criticism of life; that the greatness of a poet lies in his powerful and beautiful application of ideas to life — to the question, How to live. Morals are often treated in a narrow and false fashion, they are bound up with systems of thought and belief which have had their day, they are fallen into the hands of pedants and professional dealers, they grow tiresome to some of us. We find attraction, at times, even in a poetry of revolt against them; in a poetry which might take for its motto Omar Khayam's words: "Let us make up in the tavern for the time which we have wasted in the mosque." Or we find attractions in a poetry indifferent to them, in a poetry where the contents may be what they will, but where the form is studied and exquisite. We delude ourselves in either case; and the best cure for our delusion is to let our minds rest upon that great and inexhaustible word life, until we learn to enter into its meaning. A poetry of revolt against moral ideas is a poetry of revolt against life; a poetry of indifference towards moral ideas is a poetry of indifference towards life.

What is Art? (1897)

The Spiritual Espousals (c. 1340)
Context: You should watch the wise bee and do as it does. It dwells in unity, in the congregation of its fellows, and goes forth, not in the storm, but in calm and still weather, in the sunshine, towards all those flowers in which sweetness may be found. It does not rest on any flower, neither on any beauty nor on any sweetness; but it draws from them honey and wax, that is to say, sweetness and light-giving matter, and brings both to the unity of the hive, that therewith it may produce fruits, and be greatly profitable. Christ, the Eternal Sun, shining into the open heart, causes that heart to grow and to bloom, and it overflows with all the inward powers with joy and sweetness. So the wise man will do like the bee, and he will fly forth with attention and with reason and with discretion, towards all those gifts and towards all that sweetness which he has ever experienced, and towards all the good which God has ever done to him. And in the light of love and with inward observation, he will taste of the multitude of consolations and good things; and will not rest upon any flower of the gifts of God, but, laden with gratitude and praise, will fly back into the unity, wherein he wishes to rest and to dwell eternally with God.
