If there are any, what are the differences in meaning between the statements ''I am a materialist person'' and ''I am a materialistic person'' ?
*Context: In a conversation on philosophical materialism that concerns matter and the universe I want to describe my viewpoint, which leans towards materialism due to its properties. However my viewpoint also has some properties which I am not sure can be considered materialist.
Due to being unsure whether my entire viewpoint fits with straightforward materialist understanding I want to avoid describing myself as ''I am a materialist person'', instead I am using the phrase ''I am a materialistic person''. Is using the word ''materialistic'' in such context correct?
So far I've received feedback that I must avoid using ''materialistic'' because it can be misunderstood with excessive material possession in pejorative way. However context is a scientific and philosophical discussion about universe and it is clear for everyone in the conversation what materialism means. The word ''materialistic'' is also used in such context in philosophical/ontological area: enter link description here There are many Google hits as such ''materialistic scientist'', ''materialistic scholar'' etc. as well.
Common description of suffix ''-ic'' is ''of or pertaining to or relatedeness''. Description below also indicates ''having some characteristics of opposed to simple attributive use'' :enter link description here For example the word ''metallic'' doesn't have to imply substance (objects made of metal). Any sort of resemblance to metal is enough to describe something as ''metallic'' as such ''metallic vase'' (no metal substance) or metallic voice: enter link description here
Therefore, in the context above
Does ''materialistic'' strictly mean ''materialist''? Why, why not?
Can I add suffix ''-ic'' to the word ''materialist'' when there is any resemblance to ''materialist'' such as materialist-like viewpoint?
