When experience has once given us a competent knowledge of human affairs, and has taught us the proportion they bear to human passion, we perceive, that the generosity of men is very limited, and that it seldom extends beyond their friends and family, or, at most, beyond their native country. Being thus acquainted with the nature of man, we expect not any impossibilities from him

Context

“Having thus explained the origin of that praise and approbation, which attends every thing we call great in human affections; we now proceed to give an account of their goodness, and shew whence its merit is derived. When experience has once given us a competent knowledge of human affairs, and has taught us the proportion they bear to human passion, we perceive, that the generosity of men is very limited, and that it seldom extends beyond their friends and family, or, at most, beyond their native country. Being thus acquainted with the nature of man, we expect not any impossibilities from him; but confine our view to that narrow circle, in which any person moves, in order to form a judgment of his moral character. When the natural tendency of his passions leads him to be serviceable and useful within his sphere, we approve of his character, and love his person, by a sympathy with the sentiments of those, who have a more particular connexion with him.” source
