On the mixed tax [WWP43] (even when a fixed & published % of the tax was for war, led some Qs astray):

They had consulted Friends’ writings, &c., and come to the conclusion that as this was a mixed tax, and as Friends had always paid taxes, part of which had gone to support a military establishment, it was better to pay this tax, and make no trouble about it....

...

The war and the bounty tax was paid by all this class of Friends; the blighting assertion being often heard from them “that the tax demanded was a mixed tax, and they could not avoid paying it.”

...

The taxes being so levied that they could not distinguish in regard to them, when the nation was engaged in war they believed it was more consistent with the Divine will and safer for them to suffer distraint and loss of property than to pay the mixed taxes.

Nathan Hall chided Maule for only withholding the military-designated % of the tax, saying something like it was like trying to avoid alcohol by only drinking 75% of a bottle of 50-proof liquor.  (See also: Milton Mayer)

Also, critics question whether Maule, by paying business & excise taxes, is paying mixed taxes that are just as bad. Maule responds: (WWP52)

The arguments used in reference to what disposition the officers of the law might make of the money collected appeared to me to be valueless. What has any one to do with this kind of reasoning who is concerned to bear a testimony against war? Besides, I am not accountable for the acts of other men: if I owe a just debt, I must pay it; if the person receiving the money uses it for a bad purpose, the accountability is with him; but if he demand money of me avowedly to be used in any way to the plundering of my neighbor, destroying his property, or tak-ing his life, then if I furnish money thus demanded I become an accomplice in the evil work and accountable for the sin. I consider our civil taxes a just debt that should be promptly paid, but I am satisfied that no human authority has either a moral or a religious right to demand of me money or means of any kind to aid in destroying the lives and property of my fellow-men. The teachings of the Saviour of mankind forbid me to comply with such demands if made, and His precepts also require me to submit peacefully to the powers that be, in whatever course they may take in regard to my person or property on such account.

[also on WWP52-53, whether Jesus's "pay unto Cesar" covers paying a mixed tax that is used for military & other purposes]

WWP55, Maule distinguishing bonds from seignorage:

The bonds used by the government I had no doubt were issued for war purposes; and it appeared to me that buying them was, in effect, loaning, and, so far, voluntarily furnishing means for carrying on the war; and entirely a different thing from using the public money in ordinary business.

More Maule, WWP60:

I believe there are many snares to entrap the unwary in this thing, and not the least of these is the argument so much used, that it is so blended with all business that none can keep entirely clear of it. The framers of our discipline did not see it so blended. I many times hear it said by these who maintain no testimony against war taxes, and said, I apprehend, for the purpose of setting at naught the whole testimony, that the duties, the government money, &c., are all the same thing as paying the tax; but in the light of Truth they are very different things.

WWP61:

As to the application of the money when I pay the tax required for civil purposes, I am not accountable for the acts of the officers of the law, but when the demand is presented to me to pay so much for the war, if I do this voluntarily and understandingly, I put my own hand to the work of war and bloodshed, which I feel assured Christianity forbids.

The tax collector responds to Maule:

The... act, which I read, conclusively proves to my mind that in the course you propose you would voluntarily pay the war tax on the amount so paid. Why not view it as paid by compulsion when I demand from you at the counter your whole tax? Very few men voluntarily and cheerfully pay their tax; it is only the fear of the law and the knowledge that their property would suffer if not paid that causes many to pay taxes.

Maule on voting:

When the country was engaged in war I became fully convinced that to profess, as I was doing, to maintain a Christian testimony against war by declining to pay the tax required to support it, and at the same time to vote in the election of men whose legal duty, on accepting office, required them, in various ways, to direct and promote it, was inconsistent in itself and incompatible with the principles of the Gospel; since that time, more than twenty years, I have not voted.

WWP65 (Maule):

I know the reasons and excuses which were given and made by the leaders of the people who caused them to err: that these taxes were mixed and could not be distinguished or separated from the other taxes, &c.; but thou knowest this was not true, for they were carefully divided and described, and plainly set before us, so that he that ran might read; and that for the war and bounty was not mixed with any other, until those who paid it voluntarily mixed it themselves, and thereby made it their own act to pay the price for men to go forth to the field of human slaughter.
