One might ask why tobacco is legal and marijuana not. A possible answer is suggested by the nature of the crop.

I don't use the social media but I can see the effects in my own correspondence. I get a ton of correspondence. It used to be hard copy and now it's a very limited amount of actual letters people write. So it's mostly email.

From 1962 to 1965 the US was dedicated to try to prevent the independence of South Vietnam, the reason was of course that Kennedy and Johnson knew that if any political solution was permitted in the south, the National Liberation Front would effectively come to power, so strong was its political support in comparison with the political support of the so-called South Vietnamese government.

The obvious one, in a market system, in a really functioning one, whoever's making the decisions doesn't pay attention to what are called externalities, effects on others. I sell you a car, if our eyes are open we'll make a good deal for ourselves but we're not asking how it's going to affect her [over there.] It will, there'll be more congestion, gas prices will go up, there will be environmental effects and that multiplies over the whole population. Well, that's very serious.

It's fine to criticize somebody else's crimes and misdeeds, but you don't talk about your own. The only exception is a country that is defeated. And even that is rather nuanced.

I am not sure just what Marx had in mind when he wrote that "philosophers have hitherto only interpreted the world in various ways; the point is to change it." Did he mean that philosophy could change the world, or that philosophers should turn to the higher priority of changing the world? If the former, then he presumably meant philosophy in a broad sense of the term, including analysis of the social order and ideas about why it should be changed, and how. In that broad sense, philosophy can play a role, indeed an essential role, in changing the world.

The United States is alone among all the countries in that it does not permit US military forces to be under any threat. Other countries are willing to have forces in peace-keeping operations where they sometimes are under threat, but the US is not willing to do that.
