Petrus Borel said this quote

To get rich, one must have but a single idea, one fixed, hard, immutable thought: the desire to make a heap of gold. And in order to increase this heap of gold, one must be inflexible, a usurer, thief, extortionist, and murderer! And one must especially mistreat the small and the weak!And when this mountain of gold has been amassed, one can climb up on it, and from up on the summit, a smile on one’s lips, one can contemplate the valley of poor wretches that one has created.

~ Petrus Borel

In Paris there are two dens, one for thieves, the other for murderers. The den of thieves is the Stock Exchange; the den of murderers is the Courthouse.

~ Petrus Borel

I do not believe that one can become rich without being a shark, a sensitive man will never amass wealth.

~ Petrus Borel
