ambition, pusillanimity, frugality, &c., with reference to the course of conduct they prompt to. Then he comes to a favourite subject, the mistaken courses whereinto men fall that are ignorant of natural causes and the proper signification of words. The effect of ignorance of the causes of right, equity, law, and justice, is to make custom and example the rule of actions, as with children, or to induce the setting of custom against reason, and reason against custom, whereby the doctrine of right and wrong is perpetually disputed, both by the pen, and by the sword. Again, taking up ignorance of the laws of nature, he is led on to the subject of natural Religion, and devotes also the whole of Chapter XII. to Religion and kindred topics. In Chapter XIII., he deals with the natural condition of Mankind, as concerning their Felicity and Misery. All men, he says, are by nature equal. Differences there are in the faculties of body and mind, but, when all is taken together, not great enough to establish a steady superiority of one over another. Besides even more than in strength, men are equal in _prudence_, which is but experience that comes to all. People indeed generally believe that others are not so wise as themselves, but 'there is not ordinarily a greater sign of equal distribution of anything than that every person is contented with his share.' Of this equality of ability, the consequence is that two men desiring the exclusive possession of the same thing, whether for their own conservation or for delectation, will become enemies and seek to destroy each other. In such a case, it will be natural for any man to seek to secure himself by anticipating others in the use of force or wiles; and, because some will not be content with merely securing themselves, others, who would be content, will be driven to take the offensive for mere self-conservation. Moreover, men will be displeased at being valued by others less highly than by themselves, and will use force to extort respect. Thus, he finds three principal causes of quarrel in the nature of man--_competition, diffidence_ (distrust), and _glory_, making men invade for gain, for safety, and for reputation. Men will accordingly, in the absence of any power to keep them in awe, be in a constant state of war; by which is meant, not actual fighting, but the known disposition thereto, and no assurance to the contrary.
