tain Uniformity in the Operation of the Sun, Rain, and Earth, towards the Production of Vegetables; and Experience teaches the old Practitioner the Rules, by which this Operation is govern'd and directed?
We must not, however, expect, that this Uniformity of human Actions should be carry'd such a Length, as that all Men, in the same Circumstances, should always act precisely in the same Manner, without any Allowance for the Diversity of Characters, Prejudices, and Opinions. Such a Uniformity, in every Particular, is found in no Part of Nature. On the contrary, from observing the Variety of Conduct and Behaviour in different Men, we are enabled to form a greater Variety of Rules and Maxims, which still suppose a Degree of Uniformity and Regularity.
Are the Manners of Men different in different Ages and Countries? We learn thence the great Force of Custom and Education, which mold the human Mind from its Infancy, and form it into a fix'd and establish'd Character. Is the Behaviour and Conduct of the one Sex very unlike that of the other? 'Tis from thence we become acquainted with the different Characters, which Nature has impress'd upon the Sexes, and which she preserves with Constancy and Regularity. Are the Actions of the same Person much diversify'd in the different Periods of his Life, from Infancy to oldAge?
