“Fast drivers can see no further than slow drivers, but they must look further down the road to time their reactions safely. Similarly, people with great projects afoot habitually look further and more clearly into the future than people who are mired in day-to-day concerns. These former control the future because by necessity they must project themselves into it; and the upshot is that, like ambitious settlers, they stake out larger plots and homesteads of time than the rest of us. They do not easily grow sad or old; they are seldom intimidated by the alarms and confusions of the present because they have something greater of their own, some sense of their large and coherent motion in time, to compare the present with.”

Context: It is a step to have it proved, that there must be something in the world more than what we see. It is a further step to know, that, amongst the invisible things of nature, there must be an intelligent mind, concerned in its production, order, and support. These points being assured to us by Natural Theology, we may well leave to Revelation the disclosure of many particulars, which our researches cannot reach, respecting either the nature of this Being as the original cause of all things, or his character and designs as a moral governor; and not only so, but the more full confirmation of other particulars, of which, though they do not lie altogether beyond our reasonings and our probabilities, the certainty is by no means equal to the importance. The true theist will be the first to listen to any credible communication of Divine knowledge. Nothing which he has learned from Natural Theology, will diminish his desire of further instruction, or his disposition to receive it with humility and thankfulness. He wishes for light: he rejoices in light. His inward veneration of this great Being, will incline him to attend with the utmost seriousness, not only to all that can be discovered concerning him by researches into nature, but to all that is taught by a revelation, which gives reasonable proof of having proceeded from him.

As quoted in Elevator Music (1994) by Joseph Lanza
Context: I began to become an adult when I was 24 and got married and had children. That matures you, but I wouldn't say I was fully an adult until I was in my forties. The trouble with the whole adult debate is that if you're asking 18-year-olds to go out and fight wars for you then you can't deny them adult rights even though in sorts of other ways they wouldn't qualify until they were about 25. These days adolescence stretches much further into adulthood than it used to. There's no longer any encouragement to be mature.
