RT Article T1 Beyond the Material and the Mechanical: Occam's Razor Is a Double-Edged Blade JF Zygon VO 30 IS 2 SP 249 OP 266 A1 Ulanowicz, Robert E. LA English PB Wiley-Blackwell YR 1995 UL https://www.ixtheo.de/Record/1827951052 AB Abstract. To confine scientific narrative to only material and mechanical causes is to ensure incomplete and at times contrived descriptions of phenomena. In the life sciences, and particularly in the field of ecology, causality takes on qualitatively distinct forms at different hierarchical levels. The notion of formal cause provides for entirely natural and quantitative explanations of ecosystem behavior.
