The way of fortune is like the milky way in the sky; which is a meeting, or knot, of a number of small stars, not seen asunder, but giving light together : so are there a number of little and scarce discerned virtues, or rather faculties and customs, that make men fortunate.
For first of all we must prepare a Natural and Experimental History, sufficient and good; and this is the foundation of all; for we are not to imagine or suppose, but to discover, what nature does or may be made to do.

Nor do apophthegms only serve for ornament and delight, but also for action and civil use, as being the edge-tools of speech which cut and penetrate the knots of business and affairs: for occasions have their revolutions, and what has once been advantageously used may be so again, either as an old thing or a new one.
Generally, youth is like the first cogitations, not so wise as the second. For there is a youth in thoughts, as well as in ages. And yet the invention of young men, is more lively than that of old; and imaginations stream into their minds better, and, as it were, more divinely.
