"What though on hamely fare we dine,
Wear hodden grey, an' a that;
Gie fools their silks, and knaves their wine;
A Man's a Man for a' that:
For a' that, and a' that,
Their tinsel show, an' a' that;
The honest man, tho' e'er sae poor,
Is king o' men for a' that."

Burns (b. 1759-01-25, d. 1796-07-21),
"A Man's a Man for A' That", 1795
[I tried to find a Burns quotation about trees, since Tu B'Shvat starts this evening, but I didn't find a suitable one in time.]
