actually, assumptions are required to make deductions.

basic rule of inference.

there's nothing shameful with being wrong in your assumptions, either. what's important is that you state them at the start, so that the reader knows what they are.

they are, after all, assumptions. they are required. but, they are also arbitrary.

i mean, if you think that you can present to me an argument that is void of assumptions, be prepared for me to find one.

that's ok. as mentioned: assumptions are necessary. what's important is knowing where they are.
