Many able Gardeners and Husbandmen are yet Ignorant of the Reason of their Calling; as most Artificers are of the Reason of their own Rules that govern their excellent Workmanship. But a Naturalist and Mechanick of this sort is Master of the Reason of both, and might be of the Practice too, if his Industry kept pace with his Speculation; which were every commendable; and without which he cannot be said to be a complete Naturalist or Mechanick.
William PennIf thou wouldst conquer thy weakness, thou must never gratify it. No man is compelled to evil: his consent only makes it his. It is no sin to be tempted, but to be overcome.
William PennClear therefore thy head, and rally, and manage thy thoughts rightly, and thou wilt save time, and see and do thy business well; for thy judgment will be distinct, thy mind free, and the faculties strong and regular.
