            		In challenging the belief that the truth is obvious, it is 
					useful to leave the charged world of political philosophy 
					for a moment and begin by enumerating some of the many ways 
					in which physical reality is counter-intuitively complex. We 
					all share the expectation, for instance, that a heavier 
					object will fall faster than a lighter one, and we are all 
					shocked when we learn, as children, that this is not the 
					case. The reality is not as simple as it appears, because 
					complicating factors like air resistance vary according to 
					an object's shape and density.  
					 
          Well, no less an authority 
					than Einstein said that "Politics is more difficult than 
					physics."(1) Social reality has its share of complicating factors too, 
					perhaps even more so than physical reality. In addition, 
					social reality cannot be experimented upon as readily as 
					physical reality. The social world does not fit as easily 
					into a laboratory, and ethical concerns prevent social 
					scientists from manipulating people the way physical 
					scientists manipulate inanimate matter. Given the added 
					difficulties of examining and trying to understand social 
					reality, is it any wonder, for instance, that many people 
					fail to appreciate (or refuse to accept) that raising the 
					minimum wage increases unemployment? When people come to 
					realize that the truth is not so easy, they will be more 
					willing to keep an open mind, to listen to what others have 
					to say, and to check their premises against reality as best 
					they can. 
					 
					          
            		Let us not be fooled into thinking that this belief is any 
					less prevalent within the freedom movement than it is among 
					other people. Believing that our ideas are self-evidently 
					true will prevent us from discovering our own errors, just 
					as it can prevent others from discovering theirs. 
					Furthermore, it will prevent us from communicating our ideas 
					effectively if we cannot understand or appreciate what leads 
					others to their different beliefs. We may end up going so 
					far as to ascribe evil motives to those with whom we 
					disagree if we are unable even to imagine that someone could 
					in good faith fail to see what is so obvious. Needless to 
					say, calling people evil is not the best way to foster 
					fruitful debate, or to convince others of the soundness of 
					our ideas. We must remember that the negative consequences 
					of illiberal policies, which may seem obvious to us, are not 
					in fact self-evident.

							 8) Morality must be enforced  | 
						 
					 
					
                  
            Between social conservatives on the right and tobacco 
		prohibitionists on the left, it sometimes seems as if everyone wants to 
		impose his or her version of morality on everyone else. After all, if it 
		makes sense to protect us from things like murder, assault, and theft, 
		why shouldn't our representatives in government also protect us from 
		other sinful or harmful activities like pornography and smoking? These 
		self-righteous souls have a clear vision of the good life, and they want 
		you and me to share that life, whether we like it or not. I don't know 
		whether they have good intentions or not – whether they are motivated by 
		a desire to help others or merely by a desire to control them, or by 
		some combination of these and other impulses – and I don't much care. 
		What matters is whether what they are saying makes sense, and whether 
		the results of their actions are actually good. It doesn't, and they 
		aren't. 
		 
		          
            Why doesn't it make sense to treat pornography and smoking the same 
		way we treat murder, assault, and theft? Because these latter acts are 
		clear instances of aggression by one party causing real, unquestionable 
		harm to another's person or property. As actual crimes, they merit 
		retaliation in kind, and the use of defensive force against the 
		aggressor is justified. Pornography and smoking, however, are just as 
		clearly not instances of one party initiating the use of force against 
		another. As long as those who participate in these activities do so 
		voluntarily, no retaliation by the government or anyone else is 
		justified, period. (Of course, to the extent that it happens, forcing 
		someone to participate in the production of pornography is a crime, just 
		as it would be a crime to force someone to work in the tobacco fields.) 
		 
		          
            The worst that can be said of things like porn and cigarettes is 
		that they are vices. Vices can harm those who partake of them, but they 
		must also be pleasurable or else no one would ever freely choose them. 
		Those who would impose their version of the good life on others think 
		they know for certain that the harms outweigh the benefits, not just for 
		them but for everyone else as well. They also assume that those harms 
		and benefits will net out the same for everyone, ignoring the simple 
		fact that people are different. (At the extreme, anti-vice crusaders may 
		believe that pleasure itself is actually bad, but I must admit I am 
		stumped about how to address such a twisted notion! It's probably best 
		just to reason with those who are less damaged.) What are the negative 
		results of prohibiting vices? It a) empowers actual criminals by 
		allowing them to profit from the black market in prohibited wares, b) 
		exposes non-criminals to added risks, and c) wastes resources that could 
		be used to fight actual crimes, or for some other purpose entirely. In 
		trying to convince those who worry about vice to allow other individuals 
		to weigh personal harms and benefits for themselves, we should try to 
		redirect their attention to these very real harms stemming from 
		prohibition itself.
