A great idea for your wife's anniversary gift would be to get her a signed copy of a philosophy book written by her favorite philosopher. Another option could be to gift her an engraved leather-bound notebook or journal where she can write her philosophical musings and thoughts. You could also consider a subscription to a popular philosophy magazine or online course where she can expand her knowledge and interact with other like-minded individuals. A personalized philosophy-themed charm bracelet or necklace would also be a great sentimental gift that she can wear every day to remind her of your love and mutual interest.
Or you can get her a star map with the date of your anniversary.
