I Remember A Passage In Goldsmith's "vicar

Where Secrecy Or Mystery Begins, Vice Or Roguery Is Not Far Off.

All Discourse Of Which Others Cannot Partake Is Not Only An Irksome Usurpation Of The Time Devoted To Pleasure And Entertainment, But, What Never Fails To Excite Resentment, An Insolent Assertion Of Superiority, And A Triumph Over Less Enlightened Understandings. The Pedant Is, Therefore, Not Only Heard With Weariness But Malignity; And Those Who Conceive Themselves Insulted By His Knowledge Never Fail To Tell With Acrimony How Injudiciously It Was Exerted.

Ignorance Cannot Always Be Inferred From Inaccuracy; Knowledge Is Not Always Present.

He That Accepts Protection, Stipulates Obedience.

The Traveler That Resolutely Follows A Rough And Winding Path Will Sooner Reach The End Of His Journey Than He That Is Always Changing His Direction, And Wastes The Hour Of Daylight In Looking For Smoother Ground And Shorter Passages.
