I disagree. The whole reason Linnaeus created taxonomies was to simplify what had to be expressed about living things, so basically to shorten the "mental code" involved. If you know something is true of all mammals, and humans are mammals, then everything that is true of all mammals is also true of all humans (but the converse isn't true; things can be true of humans that aren't true of all mammals). Of course, later on taxonomies had another purpose; Darwin and later thinkers realized that taxonomies often correspond to the actual historical evolutionary relationship between organisms. But Linnaeus himself had no evolutionary beliefs.
