Do you think there are any philosophical differences between Veganism and Vegetarianism. I realize that the definition of these words are convoluted. So please without morphing the definitions to much, and just sticking to the basic definition. What is your opinion.

My opinion is that there is one big differnce that namely being the: exploitation of animals.
If you wounder why I ask such a stupid question please read the following post

'vegetarian' if we go by its original definition meant one who abstains from eating all animal products, so what is now referred to as a 'strict vegetarian.' do you mean a lacto-ovo vegetarian? 'vegetarian' came from a word that was supposed to mean 'full of life' - i think we can agree that eggs and dairy are not full of life.

are we talking about philosophy or definiton? one could argue that the motivation behind veganism and vegetarianism is the same.

People adopt vegetarian diets for a great many different reasons. There is no single philosophical outlook vegetarians share.

Where is the "following post" you refer to?

There are many different philosophies that advocate vegetarianism, and more than one for veganism too, so this is not really possible. Perhaps you could be more specific and pick one from each?
My opinion is that there is one big differnce that namely being the: exploitation of animals.Probably a somewhat constructed/unusual example, but what if a person is keeping rescued/run-away chickens and eats their eggs, but otherwise keeps to a vegan lifestyle?

I think the difference is not so much in the philosophy as in the commitment to it.

^^^^ What Sevenseas said.

I would say vegetarians and vegans are fellow travellers, but vegans try harder. I say this as someone who doesn't call himself "vegan" yet; I resisted the temptation to get a dairy-and-egg-containing cinnamon fritter yesterday, but had a vegetable biryani which contained ghee at dinner. (I had forgotten to ask if it had ghee, and if they could leave it out and substitute oil).

I think most vegetarians end up following a more vegan lifestyle a some point. It seems like the next logical step.

I think the difference is not so much in the philosophy as in the commitment to it.

QFT.
