When you have overcome one temptation, you must be ready to enter the lists with another.As distrust, in some sense, is the mother of safety, so security is the gate of danger. A man had need to fear this most of all, that he fears not at all.
Thomas Brooks, p. 532. reported in Josiah Hotchkiss Gilbert,Dictionary of Burning Words of Brilliant Writers (1895).
Distrust is an acquired feeling — we never doubt till we have been deceived ...
A certain amount of distrust is wholesome, but not so much of others as of ourselves; neither vanity nor conceit can exist in the same atmosphere with it.
