Give me a scholar, therefore, who is able to think and to write, to look with an eye of discernment into things, and to do business himself, if called upon, who hath both civil and military knowledge; one, moreover, who has been in camps, and has seen armies in the field and out of it; knows the use of arms, and machines, and warlike engines of every kind; can tell what the front, and what the horn is, how the ranks are to be disposed, how the horse is to be directed, and from whence to advance or to retreat; one, in short, who does not stay at home and trust to the reports of others: but, above all, let him be of a noble and liberal mind; let him neither fear nor hope for anything; otherwise he will only resemble those unjust judges who determine from partiality or prejudice, and give sentence for hire: but, whatever the man is, as such let him be described.
