There are three successive states of morality answering to the three principal stages of human life; the personal, the domestic, and the social stage.

There are three stages in this journey that I have been on. The first. the social science stage; the second, the psychedelic stage; and the third, the yogi stage.

I have found that there are three stages in every great work of God: first, it is impossible, then it is difficult, then it is done.

Something he had heard some wise man say. About the three stages of empire, the three generations. First came the conquerors, unstoppable in war. Then came the administrators, who bound it all together into one apparently unshakable, immortal edifice. Then came the wasters, who knew no responsibility and squandered the capital of their inheritance upon whims and vices. And fell to other conquerors.

Every technology goes through three stages: first a crudely simple and quite unsatisfactory gadget; second, an enormously complicated group of gadgets designed to overcome the shortcomings of the original and achieving thereby somewhat satisfactory performance through extremely complex compromise; third, a final stage of smooth simplicity and efficient performance based on correct understanding of natural laws and proper design therefrom.

Aristocracy has three successive stages: the age of superiority, the age of privilege, and the age of vanity. Once through with the first, it degenerates into the second, and dies out in the third.

Each work has to pass through these stages—ridicule, opposition, and then acceptance. Those who think ahead of their time are sure to be misunderstood.

I suppose the process of acceptance will pass through the usual four stages: i) this is worthless nonsense; ii) this is an interesting, but perverse, point of view; iii) this is true, but quite unimportant; iv) I always said so.

Every worthwhile accomplishment, big or little, has its stages of drudgery and triumph: a beginning, a struggle, and a victory.

It lays down, as is generally known, that our speculations upon all subjects whatsoever, pass necessarily through three successive stages: a Theological stage, in which free play is given to spontaneous fictions admitting of no proof; the Metaphysical stage, characterized by the prevalence of personified abstractions or entities; lastly, the Positive stage, based upon an exact view of the real facts of the case.

The third element alone remains — the institution itself, acting in such a way as to make social acts a state of habit and instinct. This element — history proves it — has never missed its aim, never has it acted as a double-bladed sword; and its influence has only been weakened when custom strove to become immovable, crystallized, to become in its turn a religion not to be questioned when it endeavored to absorb the individual, taking all freedom of action from him and compelling him to revolt against that which had become, through its crystallization, an enemy to progress.

Each work has to pass through these stages — ridicule, opposition, and then acceptance. Those who think ahead of their time are sure to be misunderstood.

The total institutions of our society can be linked in five rough groupings. First, there are institutions established to care for persons felt to be both incapable and harmless; these are the homes for the blind, the aged, the orphaned, and the indigent. Second, there are places established to care for persons felt to be incapable of looking after themselves and a threat to the community, albeit an unintended one: TB sanitaria, mental hospitals, and leprosaria. A third type of total institution is organised to protect the community against what are felt to be intentional dangers to it, with the welfare of the persons thus sequestered not the immediate issue: jails, penitentiaries, P.O.W. camps, and concentration camps. Fourth, there are institutions purportedly established the better to pursue some work-like tasks and justifying themselves only on these instrumental grounds: army barracks, ships, boarding schools, work camps, colonial compounds, and large mansions from the point of view of those who live in the servants' quarters. Finally, there are those establishments designed as retreats from the world even while often serving also as training stations for the religious; examples are abbeys, monasteries, convents, and other cloisters.

There are three stages in scientific discovery. First, people deny that it is true, then they deny that it is important; finally they credit the wrong person.
