“Profit can only arise upon alienation, i. e. in the act of exchange, when the seller sells more dearly than he has bought.”

“We should not look back unless it is to derive useful lessons from past errors, and for the purpose of profiting by dearly bought experience.”

“The difference between marketing and selling is more than semantic. Selling focuses on the needs of the seller; marketing on the needs of the buyer. Selling is preoccupied with the seller’s need to convert his product into cash; marketing with the idea of satisfying the needs of the customer by means of the product and the whole cluster of things associated with creating, delivering and finally consuming it.”

“The money received for sales has no other significance or value than its power to buy, and trade can only be imaged truly as an exchange of goods for goods in which the processes of selling and of buying are complementary.”

“Warriors have an ulterior purpose for their acts, which has nothing to do with personal gain. The average man acts only if there is the chance for profit. Warriors act not for profit, but for the spirit.”

“I told him that his profit is made when you buy, not when you sell.”

“The only thing that scares me more than space aliens is the idea that there aren't any space aliens. We can't be the best that creation has to offer. I pray we're not all there is. If so, we're in big trouble.”

“The act of navigation is not favourable to foreign commerce, or to the growth of that opulence which can arise from it. … As defence, however, is of much more importance than opulence, the act of navigation is, perhaps, the wisest of all the commercial regulations of England.”

“Every day, to earn my daily bread
I go to the market where lies are bought
Hopefully
I take up my place among the sellers.”

“I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and these are of our own making. Of properties we can only speak when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view.”
