The man of knowledge must be able not only to love his enemies but also to hate his friends.
I hate the word 'rendering,' as it equates to 'pouring concrete' on ideas that demand continuing dialog. 'Trade secrets' imply hoarding of knowledge.
Till the sun of knowledge shines on the ignorant masses and till all the men start hating violence, the world shall find no peace!
Hating the Yankees is as American as pizza pie, unwed mothers, and cheating on your income tax.
The only source of knowledge is experience.
