Perfect Software and other illusions about testing

is the title of an excellent book by Jerry Weinberg. As usual I'm going to quote from a few pages:
Information is neutral but people's reactions to information are rarely neutral.
I'm not in the proof business; I'm in the evidence and inference business.
A process description is just that, a description ... not of what has actually been done.
To qualify as a test, an action has to seek information that will influence an action.
Fixing under pressure tends to raise the fault-feedback-ratio.
Anyone who makes promises about the future must be some sort of devil.
Errors are made, not born.
In a moment of weakness it is difficult to resist infantile suggestions.
Good tools amplify effectiveness; if your effectiveness is negative, adding tools will amplify only the negativity.
