Vague question: I assume you mean Sir Francis Bacon? What book of his? I have no idea who Russel is...Russell?
For Bacon, here is a famous passage from "Of Studies" (1625):
Studies serve for delight, for ornament, and for ability. Their chief use for delight is in privateness and retiring; for ornament, is in discourse; and for ability, is in the judgment and disposition of business. For expert men can execute, and perhaps judge of particulars, one by one; but the general counsels, and the plots and marshalling of affairs, come best from those that are learned. To spend too much time in studies is sloth; to use them too much for ornament, is affectation; to make judgment wholly by their rules, is the humor of a scholar. They perfect nature, and are perfected by experience: for natural abilities are like natural plants, that need pruning, by study; and studies themselves do give forth directions too much at large, except they be bounded in by experience.
Notice the parallel structures, the concise word choice, and length of paragraph due to extended sentences, infinitive phrases, and use of semi-colon and colon. The passage is a mainly stuffy, as it uses logos, formal tone, some low- frequency words ("marshalling," "privateness"), and is "it"-based, objective essay writing.
