“Details that could throw doubt on your interpretation must be given, if you know them. You must do the best you can—if you know anything at all wrong, or possibly wrong—to explain it. If you make a theory, for example, and advertise it, or put it out, then you must also put down all the facts that disagree with it, as well as those that agree with it. There is also a more subtle problem. When you have put a lot of ideas together to make an elaborate theory, you want to make sure, when explaining what it fits, that those things it fits are not just the things that gave you the idea for the theory; but that the finished theory makes something else come out right, in addition.”

“Never talk with any man, or undertake any trifling employment, merely to pass the time away; for every day well spent may become a “day of salvation,” and time rightly employed is an “acceptable time.” And remember, that the time thou triflest away, was given thee to repent in, to pray for pardon of sins, to work out thy salvation, to do the work of grace, to lay up against the day of judgment a treasure of good works, that thy time may be crowned with eternity.”
― Jeremy Taylor, Holy Living and Dying with Prayers
