Verily, Allah enjoins justice, and the doing of good to others; and giving like kindred; and forbids indecency, and manifest evil, and wrongful transgression. (The Holy Quran, an-Nahl 16:91) This verse sets forth three gradations of doing good. The first is the doing of good in return for good. This is the lowest gradation and even an average person can easily acquire this gradation that he should do good to those who do good to him. The second gradation is a little more difficult than the first, and that is to take the initiative in doing good out of pure benevolence. This is the middle grade. Most people act benevolently towards the poor, but there is a hidden deficiency in benevolence, that the person exercising benevolence is conscious of it and desires gratitude or prayer in return for his benevolence. If on any occasion the other person should turn against him, he considers him ungrateful. On occasion he reminds him of his benevolence or puts some heavy burden upon him. The third grade of doing good is graciousness as between kindred. God Almighty directs that in this grade there should be no idea of benevolence or any desire for gratitude, but good should be done out of such eager sympathy as, for instance, a mother does good to her child. This is the highest grade of doing good which cannot be exceeded. But God Almighty has conditioned all these grades of doing good with their appropriate time and place. The verse cited above clearly indicates that if these virtues are not exercised in their proper places they would become vices.
Mirza Ghulam Ahmad
Atheism ... that bugbear of women and fools ... is the very top and perfection of free-thinking. It is the grand arcanum to which a true genius naturally riseth, by a certain climax or gradation of thought, and without which he can never possess his soul in absolute liberty and repose.
The literal record was not a hopelessly and imperfect fraction of truly insensible gradation within large populations but an accurate reflection of the actual process identified by evolutionists as the chief motor of biological change. The theory of punctuated equilibrium was, in its initial formulation, little more than this insight adumbrated.

After having produced aquatic animals of all ranks and having caused extensive variations in them by the different environments provided by the waters, nature led them little by little to the habit of living in the air, first by the water's edge and afterwards on all the dry parts of the globe. These animals have in course of time been profoundly altered by such novel conditions; which so greatly influenced their habits and organs that the regular gradation which they should have exhibited in complexity of organisation is often scarcely recognisable.
The mastery of one's phonemes may be compared to the violinist's mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbor's renderings indulgently, mentally rectifying the more glaring inaccuracies.

Depth, in a pictorial, plastic sense, is not created by the arrangement of objects one after another toward a vanishing point, in the sense of the Renaissance perspective, but on the contrary (and in absolute denial of this doctrine) by the creation of forces in the sense of push and pull . Nor is depth created by tonal gradation (another doctrine of the academician which, at its culmination, degraded the use of color to a mere function of expressing dark and light).
