Context

“nature has given to it, as to all others, matter enough of its own to make advantage of, and subjects proper enough where it may either invent or judge. Meditation is a powerful and full study to such as can effectually taste and employ themselves; I had rather fashion my soul than furnish it. There is no employment, either more weak or more strong, than that of entertaining a man’s own thoughts, according as the soul is; the greatest men make it their whole business, “Quibus vivere est cogitare;” [“To whom to live is to think.”—Cicero, Tusc. Quaes., v. 28.] nature has therefore favoured it with this privilege, that there is nothing we can do so long, nor any action to which we more frequently and with greater facility addict ourselves.” source
