For those who dislike the archaic spelling in Hobbes, this edition with modernized text and spelling is the one for them. The opening sentence suffices to show the difference. The following is the original text:
"Concerning the Thoughts of man, I will consider them first Singly, and afterwards in Trayne, or dependence upon one another." (With Singly and Trayne in italics)
The modernized text in this edition is:
"Concerning the thoughts of man, I will consider them first singly, and afterwards in train, or dependence upon one another." (No italics)
There is a decent introduction by Gaskin, a bibliography, an index and explanatory notes, and this edition is very competitively priced.
As a student at Oxford I chose an optional paper "Political theory from Hobbes". It was "from Hobbes" because modern political philosophy begins with him. Before Hobbes, writers for centuries had accepted the divine right of kings or did not consider the origins of government. In Hobbes we find concepts that became standard in political thought: human nature, state of nature, social contract, absolute and limited government, civil disobedience, censorship, etc.
Hobbes supposes that organized society is a choice. The alternative is the "state of nature" with both a "right of nature" and "laws of nature", but Hobbes uses the terms in an idiosyncratic way. The "right of nature" is "the liberty each man has, to use his own power...for the preservation of his own life" and doing anything that is necessary to achieve this. In addition there are a number of "laws of nature". The first dictates that each person should seek to live with others in peace, and the second is that each person should only retain the right to as much liberty as he is willing to permit others. These (and other laws that follow from them) are found by reason and are utilitarian rather than prudential. Morality does not enter into it. Hobbes is simply saying that if men think about their situation, reason tells them that giving up their natural rights in exchange for others doing the same is the best means of self-preservation, even though this is contrary to human nature.
On human nature Hobbes is cynical. Men have the power of reason that suggests possible advantages of co-operation but this is outweighed by instinct. Men are competitive and selfish. They are also roughly equal in ability, so no one person or group can impose his will on others. Life in the state of nature is "solitary, poor, nasty, brutish and short." Hence men are driven to create government via a pact in which all give up their natural rights to a sovereign authority, which may be either an individual or an oligarchy (Hobbes prefers the former). Hobbes uses the concept of a "social contract". It is not an historical event but a logical device to describe the ongoing basis of consent to government. Very importantly, Hobbes assigns absolute power to the sovereign. Limited government is unworkable, for men are too quarrelsome and selfish and "a kingdom divided against itself cannot stand." Hobbes was influenced by the divisive years preceding the English Civil War in which he lived. Among the ten rights Hobbes awards the sovereign the sixth is the power of censorship of opinions he deems harmful to the state. Control of religion is not among the ten rights but Hobbes later argues that the sovereign must seek to restrain discussion of religion because it is a source of conflict. As for anybody seeking to preach a new religion, he should be treated as a criminal. Hobbes was not a religious man but he could not avoid discussing the role of religion in the age in which he lived.
Are there circumstances in which people are justified in breaking the law, and is there an ultimate right of rebellion? The answer is to be found in the nature of the social contract. Men consent to an absolute ruler in order to better secure self-preservation. If a situation arises where the sovereign fails to achieve that then society is dissolved. On civil disobedience Hobbes observes that a criminal going to his execution retains his natural right to resist, but he is not saying it is a "moral" right, and in fact the sovereign is right to execute him. On conscription, Hobbes seems at first sight ambiguous because he declares that a man's natural right to protect his own life extends to refusing to die in military service if conscripted. However, further reading shows that the sovereign has the right to require people to risk their life if the existence of the state is threatened. On the other hand men should have the right to put a volunteer in their place (if one is available) and the sovereign does not have the right to demand the sacrifice of my life if the existence of the state is not threatened.
"Leviathan" is not an easy book, not helped by the fact that the English is that of a man born just 24 years after Shakespeare. However, it is an important work that makes a good study companion to Locke's "Second Treatise", which argues for limited government. Those who prefer the original to this modernized text have many choices, including the Macpherson edition.
