“People who invest make money for themselves; people who speculate make money for their brokers.”
― Benjamin Graham, The Intelligent Investor

“Outright speculation is neither illegal, immoral, nor (for most people) fattening to the pocketbook. More than that, some speculation is necessary and unavoidable, for in many common-stock situations there are substantial possibilities of both profit and loss, and the risks therein must be assumed by someone.* There is intelligent speculation as there is intelligent investing. But there are many ways in which speculation may be unintelligent. Of these the foremost are: (1) speculating when you think you are investing; (2) speculating seriously instead of as a pastime, when you lack proper knowledge and skill for it; and (3) risking more money in speculation than you can afford to lose.”

“It is hard to understand how a compassionate world order can include so many people afflicted by acute misery, persistent hunger and deprived and desperate lives, and why millions of innocent children have to die each year from lack of food or medical attention or social care.
This issue, of course, is not new, and it has been a subject of some discussion among theologians. The argument that God has reasons to want us to deal with these matters ourselves has had considerable intellectual support. As a nonreligious person, I am not in a position to assess the theological merits of this argument. But I can appreciate the force of the claim that people themselves must have responsibility for the development and change of the world in which they live. One does not have to be either devout or non devout to accept this basic connection. As people who live-in a broad sense-together, we cannot escape the thought that the terrible occurrences that we see around us are quintessentially our problems. They are our responsibility-whether or not they are also anyone else's.
As competent human beings, we cannot shirk the task of judging how things are and what needs to be done. As reflective creatures, we have the ability to contemplate the lives of others. Our sense of behavior may have caused (though that can be very important as well), but can also relate more generally to the miseries that we see around us and that lie within our power to help remedy. That responsibility is not, of course, the only consideration that can claim our attention, but to deny the relevance of that general claim would be to miss something central about our social existence. It is not so much a matter of having the exact rules about how precisely we ought to behave, as of recognizing the relevance of our shared humanity in making the choices we face.”

“And back in the spring of 1720, Sir Isaac Newton owned shares in the South Sea Company, the hottest stock in England. Sensing that the market was getting out of hand, the great physicist muttered that he “could calculate the motions of the heavenly bodies, but not the madness of the people.” Newton dumped his South Sea shares, pocketing a 100% profit totaling £7,000. But just months later, swept up in the wild enthusiasm of the market, Newton jumped back in at a much higher price—and lost £20,000 (or more than $3 million in today’s money). For the rest of his life, he forbade anyone to speak the words “South Sea” in his presence. 4”
