It is not difficult to conceive, however, that for many reasons a man writes much better than he lives. For without entering into refined speculations, it may be shewn much easier to design than to perform. A man proposes his schemes of life in a state of abstraction and disengagement, exempt from the enticements of hope, the solicitations of affection, the importunities of appetite, or the depressions of fear, and is in the same state with him that teaches upon land the art of navigation, to whom the sea is always smooth, and the wind always prosperous.

The mathematicians are well acquainted with the difference between pure science, which has to do only with ideas, and the application of its laws to the use of life, in which they are constrained to submit to the imperfection of matter and the influence of accidents. Thus, in moral discussions, it is to be remembered that many impediments obstruct our practice, which very easily give way to theory. The speculatist is only in danger of erroneous reasoning; but the man involved in life, has his own passions, and those of others, to encounter, and is embarrassed with a thousand inconveniencies, which confound him with variety of impulse, and either perplex or obstruct his way. He is forced to act without deliberation, and obliged to choose before he can examine: he is surprised by sudden alterations of the state of things, and changes his measures according to superficial appearances; he is led by others, either because he is indolent, or because he is timorous; he is sometimes afraid to know what is right, and sometimes finds friends or enemies diligent to deceive him.

We are, therefore, not to wonder that most fail, amidst tumult, and snares, and danger, in the observance of those precepts, which they lay down in solitude, safety, and tranquillity, with a mind unbiassed, and with liberty unobstructed. It is the condition of our present state to see more than we can attain; the exactest vigilance and caution can never maintain a single day of unmingled innocence, much less can the utmost efforts of incorporated mind reach the summit of speculative virtue.

It is, however, necessary for the idea of perfection to be proposed, that we may have some object to which our endeavours are to be directed; and he that is most deficient in the duties of life, makes some atonement for his faults, if he warns others against his own failings, and hinders, by the salubrity of his admonitions, the contagion of his example.

Nothing is more unjust, however common, than to charge with hypocrisy him that expresses zeal for those virtues which he neglects to practise; since he may be sincerely convinced of the advantages of conquering his passions, without having yet obtained the victory, as a man may be confident of the advantages of a voyage, or a journey, without having courage or industry to undertake it, and may honestly recommend to others, those attempts which he neglects himself.

The interest which the corrupt part of mankind have in hardening themselves against every motive to amendment, has disposed them to give to these contradictions, when they can be produced against the cause of virtue, that weight which they will not allow them in any other case. They see men act in opposition to their interest, without supposing, that they do not know it; those who give way to the sudden violence of passion, and forsake the most important pursuits for petty pleasures, sire not supposed to have changed their opinions, or to approve their own conduct. In moral or religious questions alone, they determine the sentiments by the actions, and charge every man with endeavouring to impose upon the world, whose writings are not confirmed by his life. They never consider that themselves neglect or practise something every day inconsistently with their own settled judgment, nor discover that the conduct of the advocates for virtue can little increase, or lessen, the obligations of their dictates; argument is to be invalidated only by argument, and is in itself of the same force, whether or not it convinces him by whom it is proposed.

Yet since this prejudice, however unreasonable, is always likely to have some prevalence, it is the duty of every man to take care lest he should hinder the efficacy of his own instructions. When he desires to gain the belief of others, he should shew that he believes himself; and when he teaches the fitness of virtue by his reasonings, he should, by his example, prove its possibility: Thus much at least may be required of him, that he shall not act worse than others because he writes better, nor imagine that, by the merit of his genius, he may claim indulgence beyond mortals of the lower classes, and be excused for want of prudence, or neglect of virtue.

Bacon, in his History of the Winds, after having offered something to the imagination as desirable, often proposes lower advantages in its place to the reason as attainable. The same method may be sometimes pursued in moral endeavours, which this philosopher has observed in natural inquiries; having first set positive and absolute excellence before us, we may be pardoned though we sink down to humbler virtue, trying, however, to keep our point always in view, and struggling not to lose ground, though we cannot gain it.

It is recorded of Sir Mathew Hale, that he, for a long time, concealed the consecration of himself to the stricter duties of religion, lest by some flagitious and shameful action, he should bring piety into disgrace. For the same reason it may be prudent for a writer, who apprehends that he shall not enforce his own maxims by his domestick character, to conceal his name, that he may not injure them.
