Biases.

Wyeth, St. Georges Pine, 1967

In the course of the years, [one] imputes to each species, from his responses to their beauty or utility, and their responses to his labors for or against them, a series of attributes that constitute a character. I am amazed to learn what diverse characters different men impute to one and the same tree.  Our plant biases are indeed a sensitive index to our affections, our tastes, our loyalties, our generosities, and our manner of wasting weekends.

Aldo Leopold, from A Sand County Almanac
