  ThefactthatthehigherprinciplescomefromthesameEnvironmentasthoseoftheplant,neverthelessdoesnotimplythattheyarethesameasthosewhichenterintotheplant。Intheplanttheyarephysical,inManspiritual。Ifanythingistobeimplieditisnotthatthespiritualenergiesarephysical,butthatthephysicalenergiesarespiritual。Tocallthethingsinthephysicalworld"material"takesusnonearerthenatural,nofurtherawayfromthespiritualTherootsofatreemayrisefromwhatwecallaphysicalworld;theleavesmaybebathedbyphysicalatoms;eventheenergyofthetreemaybesolarenergy,butthetreeisitself;ThetreeisaThought,aunity,arationalpurposefulwhole;the"matter"isbutthemediumoftheirexpression。Callitall——matter,energy,tree——aphysicalproduction,andhaveweyettoucheditsultimatereality?Areweevenquitesurethatwhatwecallaphysicalworldis,afterall,aphysicalworld?Thepreponderatingviewofscienceatpresentisthatitisnot。Theveryterm"materialworld,"wearetold,isamisnomer;
